The Denver Broncos have a tough test tonight against the San Diego Chargers. The Broncos need to develop an effective running game to open up the field for Peyton Manning. If the Broncos want to do this, they may need to start relying on rookie running back Ronnie Hillman slightly more. Hillman has only had 15 carries for 47 yards on the season at this point, but that doesn't mean he isn't going to get more snaps. Hillman was the 3rd round pick for Denver out of San Diego State. The 21 year old has slowly moved up the depth chart for Denver, and is beginning to get more reps each week. After McGahee fumbled last week against New England, it isn't a stretch to believe Hillman will get more playing time tonight in the prime time spotlight.
