I watched a couple of games with Deuce Vaughn, and although he has some wiggle, and broke off some good runs in college, he also has an awful lot of plays where he gets stopped at the line of scrimmage. Due to his slight build, he gets swallowed up easily. I expect he will have an awful lot of carries in the NFL that go for zero yards - more than fans will be willing to tolerate.
He’s a great story, and I wish the kid well. But just based on their bodies of work to date, I have more trust that Ronald Jones will be a better back up to Pollard than Vaughn. Of course, I am MORE THAN WILLING to be wrong, but I don’t have a lot of hope that Vaughn will become a meaningful contributor in the Cowboys offense - at least not until he bulks up considerably. But even if he does, he still doesn’t have the break-away speed that you’d like to see in a backup gadget type RB.
Sorry to fans of Deuce, but that’s my honest opinion. I would have preferred picking Tucker out of Syracuse.
