Zeke has been a very good pass catcher as a RB.
In fact, I think he's had all of the biggest yardage pass plays at the RB position even with "more explosive" guys on the roster.
He's got the 80 yarder at Pittsburgh in 2016, a 70 yarder at San Francisco in 2017, and I believe he has a few over 30 the last couple years as well.
The drops or whatever is just a one-off to me. He's still the best RB at everything on the team and poses a threat every time he touches the ball, so I have no problem with him still being the go-to RB in those sorts of situations.
He looks quick to me this year too, so I don't really know why he hasn't had a big gain yet.
Hopefully it's just circumstance and the guy starts reeling off big plays again soon.
