I think my football IQ is bad.

I grew up playing fairly high level from 12-21. Then I joined a more casual competitive league to focus on building my business. The coaching and tactics were extremely basic.

I'm in my late 20s now and still good. I got asked from a team in one of the highest competitive leagues in my town to play for them this season.

First game was fine, we won and I only made a few minor mistakes. Skill wise I'm probably one of the better players, I'm just feel extremely out of place when it comes to football IQ.

I got so used to playing at pretty much a Sunday league level and now I feel lost tactically. The coach gave me a big pre game talk about posting and tactics but I had a hard to following along.

Where do I even start to boost my football IQ?
