Yeah, he doesn't fit as well in a passing offense. That is why Chud gave Stewart the most time on the field. Williams is weak in pass protection.
He is 29...RBs don't play often much longer. Give a thousand reasons why Williams will be an exception to that I'd you want...
And no Williams and Tolbert aren't a like...that is why in this scheme were pass protection, receiving, and running between the tackles narrows the gap between the 2.
That is just reality
Generalities with no factual basis. He had his second best average per attempt this year at 5.4. Which is 1/10 of a yard lower than his career best. lets wait until he actually drops off before proclaiming he is almost done. And who says he is weak in pass protection, if Stewart is better and that is an if,it doesn't make Williams weak. You seem too suffer from the "either or" syndrome while I prefer the "both concept.
As I said once Chud figured out how to use both of them the ground game was very effective. Both of them had 6 yards a carry and ran the ball more in the last 8 games than before the bye. If you look at it though most of the time one was more effective than the other against a particular opponent. Rarely were they both bad or great against the same opponent. At this point they provide differing styles which work differently based on what the defense is giving us. If we had missed either of them we would have struggled running the ball.
