This...he leans more to the pocket passer and has stated so.
I have seen comments like this pop up from time to time and I think it is being over "analyzed" and taken for more than what it is. Gruden and C. Kelly are actually good friends and it is well known that Gruden loves the x's and o's of the game and football is what he breaths. It more has to do with a guy like Gruden keeping up with the "times" and studying different type of attacks and schemes. There is a very good and lengthy article about Gruden that came out a couple years ago, can't remember from who but it's out there, and it speaks of Gruden always studying x's and o's and at the time of the article, he was brushing up on the triple option. Dude just loves the game and is a "football nerd"
