With kickoff less than 10 minutes away, Denver Post beat man Mike Klis reports he's still not sure who the Broncos’ starting running back will be against Baltimore. "But," Klis added, "it won’t be that big a deal because there will likely be more than one running back used in the first offensive series."

Ronnie Hillman had been the starter through the offseason and training camp. Montee Ball seemed to jump ahead following the third preseason game against St. Louis.

A third running back, Knowshon Moreno, may play as much as the other two, especially if the Broncos’ front has trouble keeping Terrell Suggs, Elvis Dumervil and Haloti Ngata out of Peyton Manning’s pocket.

In other words, relying on any of the three as your primary back would be bad news. Relying on any of the three as your RB2 or even flex is risky. Your own risk tolerance level, available options and gut feelings should be your guide here.
