Zeke can't separate on actual routes as a receiver, but he has very good hands and great spatial awareness to know where the sideline is and where the under-zone LB is lurking. He makes a great checkdown option
I've heard talk of Pollard playing WR but I just don't see it - he looked raw at it even at Memphis. I bet you Kyle Shanahan could get him a billion yards of YAC, but Pollard couldn't function as a slot in something like the 2019 Cowboys offense.
I think Pollard was originally drafted as our latest and best attempt at the RB/WR hybrid. Hands to catch short, with speed and size to go deep too. Good blocker for his size. Much better RB than expected, with great contact balance. Slot, motion, backfield. Lots of motion from Pollard to put him in his best matchup spot against the defense.
Not a pure WR, but a big matchup problem if you put an extra LB on the field against him, while a legitimate RB who you don't want matched up against a DB. And he'd still be a matchup problem for some DBs just because of his speed. If you don't have help over the top, you better be very fast.
He's a better fit as a complement to the run game with Zeke than Austin was because he's a better RB while still a legitimate deep threat.
But with Lamb getting signed, I see us playing more true 3WR than going for a RB/WR as our fifth man on offense.
Conceivable that Pollard takes snaps away from Jarwin instead, but I doubt it. That would be one fun personnel package, though. Zeke, Pollard, Gallup, Lamb, Cooper. I would love that. But that would be a whole new brand of football.
