for certain positions, yeah, I'm with you - RB, WR, etc. But, for a position where you need to develop in the wweight room (i.e. DL), I'm normally a fan of redshirting a guy to put on weight.
I acknowledge that he has loads of potential but I think people here are quick to anoint this guy based on D$'s excitement for him. I don't question D's assessment but I caution everyone to hold off crowning a kid so soon. JMO.
