Replying to (American) Football fans

Where is the appeal in watching College Football?

Being from England i don't really get why some Americans will say that they hate the NFL and only watch college football?!?

I mean why watch a lower standard of the game? Surely you'd just want to see the best around?

Do you only get attached to a college team after attending it or do you just support the local team or something?

Just seems a bit odd to me and thought i might be missing something. Nice one.
