Jackson was swimming (which is winter unless California is different) and lacrosse (spring). He probably didn't play a fall sport if Finstock didn't require it. I don't remember exactly what Jackson said either, but his attitude towards football was pretty contemptuous. Now, in a nod to the 80's Teen Wolf movie, both Peter and Derek appear to have been basketball players.

Allison had moved from somewhere in the Midwest (Chicago I think), where football would have been a bigger deal, and she probably assumed that was who the popular crowd would be until Jackson told her otherwise.
