How to Build a BJJ Scouting Report: Studying Opponents Before a Match

TL;DR. A BJJ scouting report is a short, structured breakdown of a specific opponent's tendencies, built from their recent competition footage. The goal is not to catalog everything they do — it's to identify their A-game, their reactions, and the two or three positions where you have a realistic path to score or submit. Watch at least three recent matches, log patterns by position, and turn the report into a one-page plan you can rehearse. Stay honest about what you can actually execute under pressure.

Most grapplers who look up their opponent before a tournament do it the same way: they type a name into YouTube, watch one match while scrolling their phone, and tell themselves they've "studied" them. Then they get on the mat and realize they can't remember a single thing. A real scouting report is different. It's a short, written document — ideally one page — that captures what your opponent actually does under pressure, what they react to, and where their holes are. This article walks through a simple, repeatable system for building one, even if you've never done it before and your opponent only has a handful of matches online.

Why most BJJ scouting attempts fail

Studying an opponent sounds obvious, but most hobbyist grapplers do it badly for predictable reasons.

First, they watch too much and write down too little. A single match contains dozens of grip exchanges, two or three real attacks, and a lot of neutral scrambling. Without a structure, your brain remembers the dramatic moments — the submission attempts, the big sweeps — and forgets the quiet patterns that actually decide most matches, like which side they pass to or how they react to pressure on their hips.

Second, they study opponents they have no realistic plan against. If your opponent is a national-level berimbolo specialist and you've never trained a single inversion, memorizing their entry sequence doesn't help you. A scouting report is only useful when it feeds into techniques and positions you already train.

Third, they treat the report as a prediction. Your opponent will not do exactly what the video shows. They'll adjust, they'll fatigue, and they may have added or dropped techniques since their last recorded match. A good scouting report is a bet on tendencies, not a script.

The fix is to narrow the scope: look for repeatable patterns in positions you care about, write them down in plain language, and build a short list of if-then responses you can actually drill.

Remember. You're not trying to decode your opponent's entire game. You're trying to find two or three decisions they consistently make, and prepare for those.

A simple system to build your scouting report

Here's a seven-step framework you can run in a single evening if your opponent has footage available. If they don't, skip to the end — there's a section on what to do when you have nothing to watch.

1. Confirm it's actually them, in the right context

Make sure the footage is recent (ideally within the last twelve months), at a similar weight class, and under the same ruleset you'll compete under. A gi match from three years ago in a different weight bracket is almost useless. If all you can find is older footage, note it as weaker evidence and weight it accordingly.

2. Watch three matches before writing anything

Resist the urge to pause and take notes on the first match. Watch at least three full matches with no notebook. You're looking for patterns, and patterns only emerge when you've seen the same situation happen multiple times. If you only find one match, acknowledge the small sample and don't over-commit to any conclusion.

3. Log tendencies by position

Now rewatch with a structured template. Use these four buckets:

Phase	What to log
Standing / takedowns	Preferred side, grip hand, pull-guard tendency, specific trips or singles
Guard (bottom)	Which guard they default to, favorite sweep, how they recover when passed
Passing (top)	Pass style (pressure, speed, leg-drag, knee-cut), which side they prefer
Submissions	Finishing attacks, from which positions, and how they chain them

For each bucket, write short, specific notes: "Pulls closed guard almost every match, grips cross-collar first." Not: "Has a good guard."

4. Note their reactions, not just their attacks

This is the part most people skip and it's the most useful. When their guard is being passed, what do they do? When someone grabs their collar, do they posture up or hand-fight down? When they get swept, do they turtle or try to re-guard? Reactions are far more predictable than attacks, because people drill escapes less than they drill offense.

5. Find two or three realistic windows

Look at your notes and your own game honestly. Where does their default behavior intersect with something you already do well? If they pull guard with a cross-collar grip and you've been drilling guard breaks and knee-cut passes, that's a window. If they consistently turtle after being swept and you have a solid back-take system, that's another. You want two or three of these, not ten.

6. Write the one-page plan

Condense everything into one page or one technique card. It should contain: their likely opening, your planned response, your primary scoring path, their expected reaction, and your backup. Nothing more. If it doesn't fit on one page, it's not a plan — it's a wishlist.

7. Rehearse the report with a training partner

In the two weeks before the match, run positional sparring that mirrors the scouted scenarios. Have a partner pull the opponent's typical guard, or try the opponent's favorite pass on you. You don't need the drill to be perfect — you need the decision tree to feel familiar when it happens live. A pre-tournament taper week is a natural time to rehearse these without over-training.

Remember. The point of the rehearsal is to make the decision — not the technique — automatic. You already know the techniques. You're training the choice to use them in that moment.

Common mistakes when scouting opponents

Even with a good framework, there are a few mistakes that keep coming up.

Over-indexing on one spectacular match. If your opponent hit a flying triangle in one match two years ago, that doesn't mean it's their A-game. Weigh frequency and recency more than highlight value.

Building a plan around moves you don't train. If your scouting notes conclude "their only weakness is leg locks," and you don't train leg locks, that's not a plan. Go back and find a weakness you can actually exploit, or accept that your path to winning is in neutral exchanges.

Ignoring the ruleset. A match under IBJJF rules is a different sport than a submission-only superfight. Points-based preferences — like whether an opponent chases advantages or ignores them — matter.

Scouting too late. If you build the report the night before, you have no time to drill the responses. Aim to have the report done at least two weeks out, so you can rehearse. Preparing for your first tournament is a good place to see how scouting fits into a wider ramp-up.

Not showing it to your coach. Your coach has watched hundreds of competitors and knows what reads are real and what reads are coincidence. Share the one-pager with them before you finalize it.

Scouting an opponent with no footage. This is normal at the lower end of competition. In that case, scout the division instead: watch last year's brackets at the same event and weight class, and build a report on the typical game style you'll face.

Where BJJ Memo fits in

The hardest part of scouting isn't the watching — it's turning what you watched into something you can review the week of the match. Random notes in a phone app get buried. YouTube bookmarks don't tell you why you saved the clip.

BJJ Memo is built for exactly this problem. Paste the YouTube URL of your opponent's match, and the app pulls the video with tappable timestamps so you can save the specific moments — a pass preference, a sweep, a reaction — as structured technique cards in a dedicated "scouting" folder. The revision flow surfaces those cards in the days before the match, so your notes aren't gathering dust in a Notes app. It pairs naturally with the broader workflow in our guides on studying competition footage and organizing techniques by position.

Frequently asked questions

How many matches should I watch to build a BJJ scouting report?

At least three recent matches at a similar weight and ruleset. One match is not enough to distinguish habit from coincidence. If only one or two are available, write your report with the explicit note that the sample is small and avoid over-committing to any single read.

Should I show my scouting report to my coach?

Yes. Your coach sees patterns in grappling that you'll miss as a less experienced viewer, and they know whether your planned responses are realistic given your current level. Treat the one-pager as a draft until they've looked at it.

What if my opponent has no footage online?

Scout the division instead. Watch the last two or three years of brackets at the same event, weight class, and belt level, and build a report on the typical style you'll face — common guards, common passes, common submission finishes. It won't be opponent-specific, but it's far better than going in blind.

How far in advance should I build the report?

Ideally two to three weeks before competition. That leaves time to rehearse the scouted scenarios in positional sparring and to adjust if your coach disagrees with a read. Building it the night before is almost worse than not building one at all, because you add decision load without rehearsal.

Is scouting worth it for white belts?

For your first few tournaments, probably not for a specific opponent — most white belts don't have footage, and your energy is better spent on fundamentals. But scouting the division (what guards and passes typically appear in your bracket) is useful even at white belt and takes only an hour or two.

How do I keep the report usable instead of forgetting it on match day?

Keep it to one page. Rehearse the top two scenarios in drilling. Review it the night before and the morning of, briefly. If you built a ten-page document, you built a research paper, not a game plan.

Bringing it all together

A BJJ scouting report is not a magic edge — your technique, conditioning, and composure still decide the match. But a focused one-page report, built on three matches of footage, reviewed with your coach, and rehearsed in positional sparring, gives you something most of your bracket won't have: a plan you've already run through your head. That alone makes the first thirty seconds of the match feel less chaotic, which is often enough to tilt the exchanges in your favor.

Next time you have a competitor on your bracket with footage online, paste one of their matches into BJJ Memo, save the key moments as technique cards, and build the one-pager from there — the app will surface the notes in the days before you compete so you actually walk onto the mat with them in your head. Train the responses with your coach at a legit academy; BJJ Memo helps you remember and revise, it doesn't replace mat time or qualified instruction.
