He's old, been out of football a couple years and was pretty terrible when he was in football. But he's Rex's homeboy. If you read Collision Low Crossers you would know Rex got a Hawaiian tattoo on his leg to convince Hunter to re-sign with NYJ Hunter doesn't know the offense. Tough to be a teacher when you're trying to learn it yourself. If you mean technique, well that is Kromers job.
I see this as nothing more than Rex doing Hunters bank account a favor even if it means just for training camp
