On Sunday (scroll to the bottom), I wondered whether Indianapolis Colts RB Kenton Keith's great Week Five performance (128 yards and two TDs) would show-up in reduced statistics from Jospeh Addai. My working guess was it would not. A back-up is a back-up. When the lead RB returns, then the back-up returns to his role.
Given how well Jospeh Addai had done prior to missing Week Five, I had little reason beyond curiousity to believe he would see a reduced workload. However, the confirmation of my Sunday morning musing began when Kenton Keith got all the carries during the Colts third possession which culminated with Keith punching in a three-yard TD run.
After that, both backs shared carries. Unless Addai remains injured, and all reports prior to Week Five said he was held out as a precaution and should return to full health following the team's Week Six bye, then there is the makings of the dreaded RBBC - Running Back By Comittee!
In a week that just saw Miami Dolphins' RB Ronnie Brown lost for the season, no one wants the aggravation of a reduced-usage Joseph Addai.
