As Casserly points out, Zeke has far less help than any of these guys but still produces better on the ground than they do. Zeke may get more carries but he's also targeted less in the passing game. Zeke runs behind a great OL but more than any of these other RBs he's also the focus of every defense he faces.
I'm more optimistic about the Dallas air attack than most people. I think the switch to an emphasis on precision and detail will be a good thing and we're going to see Dak and Zeke both have banner years.
That’s fair, and like I’ve said, there are too many variables IMO to definitively say one of these guys is better than the other and using total yards is one of the worst stats to use IMO. As you said, there is blocking, catching, ability to cut, downhill head on running, etc.
The one thing that I’m quite sure of is all of their total yards would be very close if they had the same amount of carries and played behind similar offensive lines with similar offensive weapons. All this ticky tacky “Zeke is much better” or “Bell is the best” is just blowing hot air at this point.
