Will never happen, but I'm positive it would fix it. Think of all the offensive linemen who have basically had to be torn down and rebuilt. Sucks to draft a player only to get real use out of him in year 3,
the NFL needs a developmental league bad. This would actually be awesome, players have the option of going to college and playing or playing the nfl minor leagues. Also they should take off the stupid 3 year out of highschool rule.
you could teach offensive linemen to do something other than spread offense blocking. You could develop QBs instead of throwing them to the wolves and praying or sitting them and praying.
