The fact of the matter is only three RBs in Cowboys History have ever led the team in rushing, and been the featured RB in the Super Bowl. They are the mercurial Duane Thomas and Hall of Famers Tony Dorsett and Emmitt Smith. Had Duane Thomas been dedicated to football, I firmly believe he had the talent to be a Hall of Fame RB. Instead he was an interesting side note and an enigma.
The inevitable conclusion that the talents that these three RBs had that allowed them to be so important to Super Bowl teams leads me to believe that if we want to clear the next plateau as a football team; we absolutely need DeMarco Murray to be as effective as at least Duane Thomas was, because minus that type of effective running we simply have not been good enough to be the top dog.
I have little doubt that Murray has the talent to be in that discussion. There are really only two questions still to answer as it pertains to Murray and his ability to push us to the next level. The obvious one is, can he stay healthy enough to play an entire season? Had Murray not been injured in 2011 I think he could have joined Tony Dorsett as our only rookie RBs with 1000 yards in a season. There is very little doubt that the team was leaps and bounds better the last two seasons with him, than they were without him. In other words, the Dallas Cowboys absolutely need Murray to be a catalyst player in 2013.
To achieve that the Cowboys need to address the second question as it pertains to Murray. Is his Offensive Line capable of being the keys to his success? The honest answer to that question is, not with the same personnel as 2012. Murray has the potential needed, but the OL, outside of Tyron Smith, does not. You can get by with one or two of the other starters keeping their jobs, but the fact of the matter is, the OL has to be improved or this team will spin its wheels all over again.
