It remains unclear who will start at running back for the Colts, and the question could stay unanswered until Week 1, reports ESPN.com. Trent Richardson is coming back from a shoulder cleanup, Vick Ballard is returning from a torn ACL, and Donald Brown is headed to free agency.

“At any point in time you'll know how we do things with the Colts, it's the best players play,” he told the website. “Iron sharp as iron. We're going to try to have the most competition at each position group and whoever wins that spot is going to be the starter and it's who is going to get us to that next level, which is Super Bowl XLIX and that's the mindset. You're either all in or all out."
