Based on the walk through today, I would suggest that's a safe bet. Pead and Cunningham look to be the "featured" RBs for tomorrow. Ganaway and Reynolds were also getting reps.
Fisher has said (more than once) that he wants to give ALL the RBs a chance to run with the #1 OLINE. Looks like its Pead and Cunningham THIS WEEK.
With SIX RBs needing to all be given a look, there just aren't enough reps to go around in any ONE GAME. So last week, Ganaway was the one who was INACTIVE, Stacy THIS week. Maybe a token appearance from Richardson.
With the 3rd Preseason generally being the one closets to the "dress rehearsal", it would figure than NEXT week, Richardson, Pead and Stacy would get the lion's share of work. That leave Game 4 vs. Baltimore and the time for the likes of Ganaway, Cunningham, and Reynolds, (yes he is still in the mix) to get their opportunity.
