The Chicago Bears clearly have their top three running backs locked in as they head into the last week of the preseason. However, they are very likely to keep a fourth back.
The decision has seemingly come down to Kerrith Whyte, a seventh-round pick in his rookie year, or Ryan Nall, a UDFA in his second NFL season. Nall spent last season on the practice squad and is looking to make an impact on the roster.
The case for Whyte is simple, though. He was drafted while Nall was not. Nall could not make the roster last season.
