The Letter grade would definitely be preferred, but it would also be nice if there was some give to this depending on how a player is performing. I'm not saying a D goes up to an A, but if you were to include the +/- with the letters like another poster suggested, someone could start out with say a B+ and be able to move that letter anywhere between a B- and an A depending on his performance after a few seasons.

It would also be cool if a player's potential could change depending on the philosophy of the team and/or what position that player ultimately plays. For example, an undersized DE in a 3-4 would have a lot more potential playing OLB then he would playing DE.
