Ohio - everyone wears the OHSAA logo throughout the season. No change for the tournaments.

Of course, there is the zipper vs snaps issue.....

Jackets are pretty much required for all varsity games in Texas, including playoff games. I say "pretty much" because other than getting yelled at (or possibly having assignments pulled), there isn't any enforcement. I've seen guys wear CCA jackets to playoff games, but I doubt that happens much.

For HS, wearing the CCA jacket around here is a big no-no.
