Good point. The answer to that is depth. I hate to see it, but a team needs bodies to practice, needs bodies to be the next man up. So while you may not be on the two deep, i know its a sorry consilation prize, but you are HELPING the team.
Like i said, its a tough situation. I can only speak in hypotheticals, but if i had a kid being recruited i would tell him to pick the school, not the coaches/system etc. Coaches get fired, coaches leave. Your chance at the NFL is SUPER SLIM. You never know what the future holds. The degree is forever though. And like someone mentioned above, i would tell my kid if possible to graduate in 3 so he has options. I did a summer session at SU, if the Football players do both, graduating in 3 is certainly possible.
