The young RBs have talent running the football. No one would argue with that.
But they might not be fully ready to pick up a blitzing 235lb linebacker at full speed. Or a 265lb defensive end that runs right around our Tackles and slams down the QB with anger.
These are the issues every year for our young RBs, and they are like 185-195lbs with "deer in the head lights look" on pass protection plays.
Even Grant struggled last year picking up a block, and Thompson got sacked within 3 seconds. Had he only made a block....
Running the ball though? Sure, there is talent to do that.
But keep in mind, Grant is running well, but he won't have the energy and physicality to be out there 1st down, 2nd down, 3rd down over and over. New guys will get there chances, and that is kinda exciting, but also scarry.
