Out of the 13 games started, 6 of those games he had below 4 ypc, his longest run in the regular season was 34 yards, and he had a whopping 7 catches in those 13 games. The only embarrassing thing I see is that he totaled Zeke's rushing TDs on 209 carries.
Again, by not statistical benchmark, is this "great". Pretending you can't find an RB giving this kind of production yearly that is a flash in a pan is crazy talk. Those numbers compare to someone like Lamar Miller, who is not a great RB.
And the only reason "great" and "elite" is "subjective" with RB is due to the fact that the position, as a whole, is incredibly unremarkable. There are very few real "elite" RBs in the league and the ones who look elite right now don't stay there for very long. You then have scrub RBs that come in, put up good numbers, and then disappear.
