I've marveled at Luck for years as a PAC-12 homer. I have always thought he was going to win at least 1 Super Bowl. I like Griffin, but I do not think he ever will.
One is a technician, a pocket passer, and once in a decade kind of player.
The other is a weapon, but also the type who takes risks that lead to injuries that shorten his danger life.
I have always and will always prefer the guy who controls the game from the pocket. I squirm every time Romo runs, which is not often. I did when Roger took off too.
