Redman wont do this, he runs down hill straight ahead. This line sucks. When Arians calls a run up the gut and there is no hole, Redman is useless, he'll run into his own linemen and fall down.
But when Arians calls a play to the right where the left guard and tight end pull to that side to help create some holes, Redman, and even Moore have had success. This is a play that the Steelers have used since the 90's. Arians has adopted it, but he rarely calls it.
People think Redman is actually shoving defensive linemen out of the way, he's not, he's just been running straight ahead and when there happens to be a hole there, he has success... He is a very good runner when he's in the open field, but he is no better than an average running back in the backfield and he just runs into his offensive linemen and falls to the ground.
