It's been five games now since C.J. Spiller took over for the injured Fred Jackson as the starting running back of the Buffalo Bills. In that time frame, his play has ranged from passable to outstanding, with Spiller amassing 533 total yards and four touchdowns in that five-game run.

Spiller followed up a career-best performance against Miami in Week 15 (91 rushing yards, 76 receiving yards, two scores) with his first career 100-yard rushing performance in Sunday's win over Denver (111 rushing yards, 27 receiving yards, one score). He's averaged 7.8 yards per touch in the past two games, including 7.2 yards per carry.

The only problem remaining with Spiller's game is that head coach Chan Gailey still isn't giving him enough carries. Even while Spiller has dominated of late, Tashard Choice has stolen 14 carries (and 18 touches overall). He's produced just 76 yards on those touches.

Given the dynamic that existed between Jackson and Spiller before Jackson's injury - and which now exists between Spiller and Choice - there are three reasonable conclusions we can reach. One: Gailey's offense can't create production for two running backs. Two: Gailey is more comfortable taking touches away from Spiller than he was from Jackson. Three: Spiller deserves more touches.
