There may be nothing wrong with him more than slower to develop than Gallup.
These players from smaller schools are evaluated in their own pools, not the one they are entering. The measurables get used a little more than judging the environment they played in.
Sometimes it takes that first season to awaken them to just what they have to do just to stay on the team. This young man discovered just about every DB is as fats, if not faster than he is, and they are fighting just as hard to make the team and make the money.
These players that get drafted after round 2, can you imagine what goes through their minds about that 2nd contract, the one their agent keeps bringing up? Making that is the difference between saying they played in the NFL and being set for life. That alone can send some young men's head spinning because they are in an area for the first time surrounded by money players. Have you ever considered the effect on these young players when they see players earning what they are and the pecking order that sets up and I think that is every bit as important to these players as the money itself.
There is more to making it than learning the route tree and with the varying degrees of maturity of these players, it can be a little mind boggling but they cannot admit that. They have all played the game of football but they haven't played NFL, its own animal. And more don't make it than do over that first 4 years.
