Apparently, SB Nation's Ryan Van Bibber is not aware of Steelers RB Isaac Redman's power over time and space.
He ranked the Steelers' running backs 30th of the 32 teams in the NFL recently, suggesting the possible absence of prize back Rashard Mendenhall will affect the team in a negative way.
Mendenhall tore his ACL at the end of the regular season, and could begin the year on the PUP list, which would keep him out of the first six games of the year.
Redman is the likely starter, and has done well in previous spot-starts in the past, including an impressive performance in a playoff loss in Denver.
The depth behind Redman, though, is a secret strength of the Steelers, and it's one of the main training camp battles to watch beginning Thursday.
Jonathan Dwyer and John Clay have logged carries during the regular season, and Baron Batch showed promise before tearing his ACL in training camp last year. Rookie Chris Rainey has great speed, and could be a contributor on special teams as well as a situational back on the offense.
While the Steelers won't likely keep all five, it is possible they do, assuming Mendenhall misses the start of the year.
That may not even happen, though, it's purely speculation.
