Why? Because he's 225-plus pounds? Or because he's the highest paid running back? If the latter, that has nothing to do with his effectiveness, just being paid doesn't automatically transfer to performance. But if he's not best in that category, how does he compare in others? Like I said, he's a complete back, how does the top back in yac do in blocking effectiveness? Or first downs made? Can't just take one stat, show he's not the top there, and conclude he's not a good back. And durability counts for a lot, does no good to have a back that can be the top rusher if he's on the sideline due to injury. Saquan, anybody?
But, if you want to pick one thing, here's another stat, from Football Outsiders:
"Running backs are ranked according to
DYAR, or Defense-adjusted Yards Above Replacement. This gives the value of the performance on plays where this RB carried/caught the ball compared to replacement level, adjusted for situation and opponent and then translated into yardage"
For 2019, the last full year and a year in which Zeke had most of the line intact:
E.Elliott DAL 324
C.McCaffrey CAR 278
M.Ingram BAL 257
A.Jones GB 207
K.Drake 2TM 202
D.Henry TEN 192
R.Mostert SF 191
D.Cook MIN 183
N.Chubb CLE 162
C.Carson SEA 130
So as you can see Zeke was not only number 1 in that stat, but far ahead of the next guy, McCaffery. Derrick Henry goes at 245 lbs, so is he the top yac guy? Even if he is, 20 or more pounds is a lot if a guy has a full head of steam...
