You should spend less time talking with aggys.
As players grow past age 18, their strengths develop in unpredictible ways. Also, coaches are going to experiment with different players in different positions for a number of reasons. If it happens a kid is better suited to play position X when he was recruited to play position Y: A) do you think the coach is going to play him other than where he will do the most for the team and b ) have you ever heard a football player say they understand they have a better shot at the NFL playing position X but they will quit unless they get to play position Y because they would rather have fun playing college ball than have a shot at a pro career? Ask your aggy friends if Tannehill should have quit when he got moved from WR to QB.
Only an aggy would say a head coach was dishonest with a recruit because he didn't explain everyone the recruit would have to compete against for playing time. No serious player gives two shits who they have to compete against. They just get out and compete.
Seriously, just ignore the aggys. They consider Kevin Sumlin to be the type of coach every program should aspire to hiring.
