Roger Craig is a great comparison, especially physically, but I think Zeke will be a better runner than Craig and maybe not quite the receiver. I think it's safe to say that Zeke will get a lot more opportunities to carry and a lot fewer to catch. Interesting, at least to me, is that both were fantastic track athletes. The only 40 time I could find for Craig is 4.8. That can't be right.
I think overall, a lot of people are underselling Elliot's strengths as a runner when comparing him to Fournette and Gurley. To me, Zeke looks like the quickest of the three, by far. He makes cuts and eludes tacklers that the other two guys just don't. I agree that Zeke probably isn't as strong, but I think he also sees the field better than Fournette or Gurley and therefore is better at exploiting holes and running lanes. I don't think it's a bad thing when a RB makes a guy miss instead of running over him. Elliot does fall forward when he's in a pile, though, which I think is more important than blowing linebackers up.
So while I like the Roger Craig comparison, Elliot looks like a bigger Lesean McCoy to me. They are both quick, with great vision and cutting ability that allows them to thrive in a zone running attack. An inch shorter and 24-lbs lighter, McCoy ran 02 faster than Elliot did at the Combine, so if the 40-yard dash is the end-all for football speed, I guess Shady is a bunch slower than Fournette/Gurley too. Although, Gurley didn't run at the Combine and Fournette is still in college, so I'm not sure the 40 comparisons are valid. The League should move the Combine to Blacksburg. Everyone would run a heck of lot faster.
