2. Deuce Vaughn
One of the first Cowboys who turned heads this training camp is rookie running back Deuce Vaughn.
Truthfully, it's easy to doubt the 21-year-old if you've never seen him play. He's only 5-foot-5 and was taken in the sixth round, highlighting how the deck's been stacked against him.
Fortunately, Vaughn isn't one to succumb to doubters. Beat reporters have been pointing out how the rookie rusher has been using his size in his favor, avoiding tackles while sliding squeeze through the smallest gaps.
Vaughn has also been motivated by the fact that the Cowboys are still determining their RB2 with Ronald Jones missing two games due to a suspension. The competition is tough with Rico Dowdle and Malik Davis also competing for the job, but it isn't like Vaughn hasn't had to prove doubters wrong before.
Even if he doesn't earn a spot in the offense, a consistent training camp and preseason could land Vaughn a special teams role. Dallas was among the best when it came to both kick and punt returns last season, so getting him involved would help continue that trend.
Besides, Vaughn's continued emergence could potentially prevent Jerry Jones from making a financial decision he'd surely regret.
