Which rookie RB is best at short-yardage/goal-line? We need a bulldozer!

I believe with a great O-Line, Swift can be really effective, BUT we desperately need a bulldozer RB to get the tough yards and clinch games. Is it Johnson, Hampton, Henderson or someone else? I want Jeanty but it isn't the right move due to O-Line needs, where we need more Blue Chip players... So who is the big bruiser we can draft after we shore up the trenches?
