THE SURE THINGS
There are only two clear-cut, no-brainer first-rounders. Both are elite, every-down runners, with excellent pass-catching skills and durable track records. They're perfect fits for their respective offenses and they don't share time with short-yardage touchdown vultures. They are the Ravens' Ray Rice and the Eagles' LeSean McCoy (top, far right).
The bubble pick in this category is Arian Foster of the Texans, who's widely regarded as the league's best runner, playing in the league's best rushing offense. Unfortunately, Foster has a history of recurring hamstring injuries, and he plays with the league's most promising backup, Ben Tate, whose 5.4 yards per rush last year ranked fourth in the NFL among those with at least 150 carries. Tate's presence makes it easy for coach Gary Kubiak to let Foster rest at the first signs of trouble. That said, Foster should be a top five pick in every draft.
