A quarterback being a great runner is far down the list to me. Scramble to buy time, yes you want that. Somebody who runs like an RB and takes those shots are not the most desirable IMO. You want someone who can carve up a defense with the brain and arm and use the legs judiciously. We want him to play til 40 not 30, the good news is he can do it. There was too much running for me this year. If you look at his yearly totals running, it went 600,500,400,700. It was trending in the right direction...400ish is what you want. He ran more out of necessity this year, long term you want an RB you can get your running yards with. Again, that is my opinion, I am sure others dont agree.
