+1 awareness is mainly what I've seen, and that's only 3-4 players on my Stanford team. I do have a +1 catch as well on my receiver, but I think this is perfectly fine. Limited progression, yet there is something there.
Also where are you checking? It's only visible when you go into the Edit Roster screen. Also it's not for very many guys at any one time.
I always check it from the depth chart screen.
