However, I would think it could be a dangerous gamble for a pro team to only draft players from certain schools because they might miss out on better talent from other schools. The interesting thing about pro teams only drafting players from certain schools is that it could turn into the catalyst that allows the P5 schools to transition their football programs into minor league affiliates assuming the school opt some day to go the "pro" route.

If you are talking about the entire Redskins' history, then you probably could add Da U, UDub, Michigan, and maybe FSU to the list.
