Kansas and Kentucky are two of the most storied basketball programs in America but they are not elite football teams. Yet, they have to populate their teams with mostly full scholarship players and expensive staffs. What if the NFL expanded to smaller markets to operate an NFL 2nd division where 19 year olds could play?
The viewers of college football would then be watching a bunch of high school aged kids and older players who are of lesser talent.
