Let me preface this by saying, IMO, EE was THE BEST RB in the NFL his first three in the league. Unfortunately, last year, and even starting with the year before last, he was just not the same player.

I understand the injuries to the Oline last year, but regardless, he did not have the burst and long speed he once had. In the Pats game this year, he did not look good, outside of the pass protection.
Yes PP is important, but he is not getting paid TOP DOLLAR for PP. On that pitch near the goal line, could not make one player miss or run him over. He tried a spin move and was taken down easily by a DB. He hardly makes anyone miss anymore.

Look, he was GREAT early on in his career, no doubt, and all Cowboy fans would love to see him continue being GREAT. But being realistic, I have doubt we see him at that high level again. Hope I'm wrong. If I'm not wrong, then we may have a RB position by committee situation.
