Combine wells and someone else for a better RB/WR or whatever, then pick up bush.
Your already stacked at RB, all you need is for bush to heal and your straight.
I know its against what everyones prediction is, but Wells and Hightower will probly be splitting alot of snaps and will probly cancel each other out. Hightower is the better reciever, goaline back, and is more versitile.
to me, all signs point to Hightower being more productive than Wells. Hightower is the starter for a reason, not motivation for wells, and hightower also improved alot last year on his YPC 4.2 that should improve as well.
