The Colts have an established starter at running back. That is Marlon Mack. He is a great players and the best back the Colts have on their roster. After him, they have a bunch of guys. They clearly don’t think much of them based on their actions this preseason.
D’Onta Foreman, who was claimed off of waivers last week, was placed on IR and replaced by Chanderick West. Foreman was brought in because the Colts didn’t like their current running back situation, and clearly West was brought in to replace him.
This very well could be just a signing to help with depth for the rest of the preseason.
