NCAA: I may be wrong but I thought I read/heard you cant work for your alma mater for 10?, maybe 15 yrs after you've graduated. - certainly that is very conference-specific
NFL: arent they designated mostly "west coast" and 'east coast' crews because where the crew mwmbers live - so travel isnt such a pain? If that is the case, it seems likely NFL would work 'home' team often. although, I would say nfl guys could care-less about having a favorite team.
