First, you are dead ass wrong about Kelly and PSU. The fact is, Paterno wanted him as a LBer. Just like his brother, Pat, played LBer in college and in the NFL.
Two, as to the game is so much more complicated now,....look at the stats from QB's today to 30 years ago. In 1991, one QB, Warren Moon, threw for over 4,000 yards. Last yearin the NFL, FOURTEEN QB's did that. I'd ventuare to say because it ismuch easier to play QB now than it ever has.
