Lighten up Francis.
Nobody is saying he is a future NFL HOFer. He's not even being compared to any NFL HOFers (btw, I must have missed Roethlisberger's induction into the HOF) - Kizer reminds some people of some other football players during their college careers with his size, poise, and athleticism. There's nothing objectionable about those types of comparisons so try to unwind your panties and grab a drink.
