The Facts: Chances are good the Broncos will have enough running backs to get them through the 2009 season. The Broncos added another one Thursday, when they signed Walker.
Diehards Line:The former Notre Dame star was an undrafted free agent who played sparingly for the Texans in 2007, and not at all in 2008 when he split time with Houston and St. Louis. ... After losing seven tailbacks to injured reserve last season, the Broncos now have eight running backs on their roster: Knowshon Moreno, Correll Buckhalter, J.J. Arrington, LaMont Jordan, Peyton Hillis, Ryan Torain, Walker and undrafted rookie Kestahn Moore. Only Hillis and Torain are holdovers from last season.
