If you're talking about reviewing previous matches in H2H, I assume you mean to see which cats you're strongest, specifically for each opponent. That, of course, is a must.

If your playoff brackets are already (almost) set in stone, you can plan for specific opponents, but that's difficult if seeding is still in flux.

Aside from that analyze your playoff schedule, noting how many games, and if you have any overbooked days you might want to stream around. Then count the games for likely playoff opponents. If you find you have fewer games than most other teams, you might look to make some trades/adds to get more games.

Yeah, gotta do some games-counting, and look to see which guys on opponents rosters play more games so you can even gameplan for which categories they might have a potential weakness/strength in for that particular week.
