Barring injury, this is a slam dunk. Davis was nothing short of outstanding in his rookie season, routinely running over and through tackles. He's shown that he belongs. Hollings has not.
Davis will get the bulk of the carries (as well as catch his share of passes) and I believe his personal goal of 2000 rushing yards is an attainable one. Having said that, I believe and hope that Hollings will flash some magic for us a few times this season.
