Battle in the Broncos backfield

As mini-camp ends for the Denver Broncos, the positional battles begin to heat up especially at the running back position. No there is no competition for the starting job, Selvin Young is pretty much locked into that position barring an injury. The real battle is taking place for his back-up, that is taking place between 2nd year back Andre Hall and the newly acquired Michael Pittman. Rookie back Ryan Torain is a distant fourth right now in the mix, which isn't a surprise as he's still got to prove himself. So who looks like they're going into training camp as the #2 guy?
