The reason i ask this is in six years he has nearly 8,000 yards rushing at 4.5 yards per carry and has never missed a game in his entire career here.He has been very durable and not to mention the last few running backs this team picked were busts in Javon Ringer and Jamie Harper. Yes on the negative side he does seem to carry for 1 or 2 yards too much before busting a huge gain which does raise his average quite a bit.He does seem like he goes down easily once he meets contact from the defense and doesn't really fight for extra yards. If we do get a new coordinator chances are they could do some things to his strength like getting him out in the open field and maybe using him more in the passing game.We also have to realize that he is and has been our only real weapon on offense. I'd love to bring in a really good back early like Bishop Sankey or a good bruiser in the Frank Gore vein that we know will fight and get those yards especially in third down situations. Bottom line should we keep or move on from Chris Johnson???
