He has never been considered one dimensional.
I am always fascinated when folks who only toted the rock in sandlot ball in 5th grade are so eager to assert what guys who have actually done it at a high level can and cannot do. Most of these people declaring what Zeke, Rico, Vaughan or whomever will be wouldn't know a sprint draw from a speed option from a 24 dive. They're just parroting. I will always stand on my assertion that the RB group will be just fine so long as the line isn't getting mauled. Runnin the ball is a skill you either have or you don't and only age, injury or just plain wear and tear can take it from you. The Cowboys have two one cut runners in Zeke and Rico. Both hit the hole hard and are tough to bring down. The biggest difference between them is Rico is quicker and Zeke is stronger. Both traits work if the line blocks. Neither of them is going to get TFL'd a lot because they will drag the first tackler with them for positive yards if the line does allow one guy to leak through. Vaughan is the change of pace speed back who the coaches will have to be creative in deploying. I think McCarthy can do that..
I also think Cook and Freeman will find a way onto the game day roster for a handful of games each. People need to accept that McCarthy aint no Chuck Knox disciple. This team will be 60% pass on offense unless they are just blowing somebody out. And in those games where they do blow the other team expect to see some house call runs from Rico and Deuce because the defense will have tapped out. Which will inevitably lead to the usual hue and cry about how they need to get all the carries and Zeke needs to be cut. But we all know what Ron White said about stupid...
