Guy i played high school football with got recruited by Pitt to play LT, because in high school he was 6'6 and 300lbs or so.

He was also absolute dogshit and never played in college. I was a backup linebacker and during our practices I'd line up at Defensive End against him specifically because I knew it'd increase my chances of playing, because I'd burn him off the snap every. Single. Play.

You can't coach size, so coaches go nuts for it, but having size doesn't mean they'll ever be able to coach you into becoming a decent player
