There's a lot of focus on Tucker's big game last year, but he did average close to 5 YPC even if you take out his production against the Saints. He averaged over 6 YPC for the season on 50 carries. Small sample size, but this dude has some juice.
Without the heart issue, Tucker likely would've been a day-2 pick. He's not a JAG. I'm open to the possibility he could be their best natural runner. Depending on how long Bucky is out and how many touches Tucker gets, we'll find out a lot more about whether he's starting material. Tucker has never been given a chance to prove it one way or the other.
