Tony Pollard leads THE ENTIRE NFL in yards after contact per rush. This is not a fluke. He was 6th last year. Zeke is 35th.
If you think that Pollard is a light runner who goes down easily and Zeke is regularly blowing people up, you need your eyes checked or just a calender that shows you its not 2017 anymore.
So, is Pollard a "bell cow"? There are a grand total of 2 players getting 20 or more carries a game. Another 6 get 15 to 20. If Pollard was getting 15 carries a game, he would be among the league leaders and could certainly handle that.
Zeke used to be a great RB. He isn't anymore. Dallas' over use of him may cost them dearly.
Pollard is really good.
