I believe you are DEAD wrong here. Look at 6 of the eight divison winners and what will you find - the BEST running backs in football(Shaun Alexander, Corey Dillon, Ahman Green, Edge, LaDanian Tomlinson, Jerome Bettis) The other two divison winners have McNabb and Vick - also running QBs. A tandem of slow, slower and slowest will NOT get anything done next year but mediocrity. This team is closer to being good than settling for mediocrity. We have the WRs, we have an okay O-line and a big question at QB, but there will NEVER be an offseason where the options at RB will be as plentiful as there are this year. Take care of that spot and all we have to worry about on O is QB.
I think we would have to be INSANE to go into next season with an average at best NFL RB in Marcel Shipp coming off a season ending injury, a below average RB in Hambrick and a WAYYYY past his prime Emmitt Smith. Emmitt's been a warrior for us this year, but think about how slow as sin he is this year and then fast forward 9 months - that ain't pretty.
Take care of the runninbg back situation and even I believe that somehow, even with Josh at QB playing as he did this season, we could sneak into the playoffs somehow.
As far as Rolle is concerned - the whole urle changes on DBs makes me very dubsious of picking a CB that high where the bust quotient is just as high there as anywhere else. Although he is a Miami guy and I love Miami players making the leap from college to the pros.
