Every kid is different. I was raised on football and may be a bigger fan than my hubby...especially when the Pats tear the Jets up :). But my kids could take it or leave it. Doesn't get them out of the Sunday ritual. We watch the games and normally go to my parents for chili, or appetizers, or some kind of bbq - depends on the weather.
If the kids don't want to watch football, they just play or read or do something else. We don't force them to watch, but it IS what is on TV.
Maybe take him to a real game? It is so different to be there and see the game...he might like it more :).
