Gold, I love you and all, and you know that. Yet how can you say if Wadley gets more carries he does even better. If Wadley had to take all the 3rd and short carries and all the carries inside the 3 yard line during the games, this would have crushed his YPC average. He didn't have to take those carries where you get 0, 1, or at most 2 yards.
Let's say that Wadley just has 10 more of those types of carries and he gets 20 yards in them (pretty good vs stacked boxes on short yardage). That would move his YPC average from 6.1 to 5.8. That isn't even close to as many short yard carries that Daniels had. He probably had 3-5 of those carries a game.
RB can go anywhere they choose. The problem is if they bounce an inside play outside too early they leave the OL exposed to holding calls. That is the only thing he needs to worry about. You can still take a play outside, just do it after the LOS. Look at the Michigan run where he broke Peppers ankles and then broke outside for 20 yards. That was a perfect run and doesn't expose the OL to a holding call. If you think this isn't what all RB are coached, then LTG, because there is a reason inside runs should go inside and outside runs should go outside.
