I agree with you that the Football board is for discussions of UCLA Football.
If you read tb's post, you'll see that his problem is not just with starting threads that have nothing to do with UCLA football but also with responses that have nothing to do with UCLA football - particularly with those that encourage other offtopic posts.
Your post was an example of this. The way to kill offtopic discussion on the football board is to take the discussion elsewhere - like I'm doing here. The Open Forum would have been a better venue for my post but it isn't open yet.
