I'm wondering, is it possible for people who never played football in high school or college to go down an lifepath which could possibly lead to a job in the NFL? Assuming the person is still young enough (mid-early twenties) and in very good athletic shape, has been an athlete in another sport, and they already attended college. Naturally this person wouldn't start out as a starter, they'd have to prove themselves. How would this be done, go back to school? can grad students play on the football team in most D1 schools? Howabout starting in amatuer and arena leagues and working maybe up to NFL europe (isn't this how some players made their way?). I'm just curious if anyone knows the details of the careers not started by drafted players.
