I wonder if there is stats on what level of players they were or became....Montana was a 3rd round pick. brady was a 6th round pick, witten was a 3rd round pick. how many went on to be HOFers? it would be interesting.
I think in the draft, in the top 10, you want to get an impact player with HOF potential. the rest is to make sure you get a solid starter. you find success if you hit on the lower rounds. so even based on these stats, if everyone is pretty equal on the 1st rounder and even 2nd rounders, those who can find the diamond in the rough in lower rounds will probably be more successful...like hitting on a kareem hunt or Alvin Kamara....
