I think you are asking the impossible when you assume it was a mistake to recruit him because no one can really know how a player will develop. They can only recruit based on film, potential, and the information they get from the people who know the kid and have seen him play in person. Maybe he had some other issues that had an effect on his development, college is a huge change in lifestyle and some people struggle. These mistakes happen all the time, look at the University of TX and that QB situation. Gilbert essetially could have picked any school in the country as the #1 QB recruit the year he graduated from HS and he is terrible. So a lot of people were wrong about him, this happens all the time.
