The Denver Broncos Web site says the RB race seems to be relatively wide open after Willis McGahee's release.
HC John Fox's Carolina teams seemingly always had two big-time backs that could rotate every other series or so -- Stephen Davis and DeShaun Foster, then Foster and DeAngelo Williams, then Williams and Jonathan Stewart.
Could it be the same situation with Montee Ball and Ronnie Hillman? Could Knowshon Moreno factor in? Something to keep an eye on as camp progresses. But to answer your question, yes, Ball will get to battle for the starting spot.
It appears Ball will have every chance to take over the starting role at some point this season. Of course it could end up being a committee with Hillman and even Moreno, who played well last year, getting chances. We rank Ball highest among the three at 25th, but he's trending down, so taking him in the fourth round where his ADP is could be a bit risky right now. It's definitely one of the bigger situations to monitor when camp starts.
