Or once he gets the snot knocked outta him a few times. Running to avoid the rush or seeing an opening to scramble for some yards is one thing, designed QB running options is another. The running QB's who make it in this league use their running ability as a last resort when all else fails, the ones who think they are going to come in and run the ball all over the place for yardage like they did in college are in for a rude awakening and don't last long. Jackson throws a nice ball and can run, as I said, I suspect he'll be running less and less as time passes and run only out of necessity. I don't know of a team that will want their star QB risking injury by running the ball all of the time, injuries are inevitable and you don't want to risk your star asset.
