...not that much better, OT, unless it's a gamebreaker as a receiver too, like McCaffery.
Pollard is a really good RB. And Pollard would look as good as McCaffery as a runner if he was a Niner, and he has almost as good as hands as McCaffery (yes, McCaffery is a better route runner...though we haven't asked Pollard to do much catching beyond being in the flat, a fault of our OC). So, I believe it's mostly the scheme, play designs and more consistent offensive line play. I noticed over the last few weeks that the Niners and Cowboys run similar stretch plays consistently. But there's a big difference in its effectiveness...the Niners handoff is closer to the LOS and as soon as McCaffery gets it, he turns it up quickly to get yards. The Cowboys hand it off further back (by only 2 or 3 yards), and then they want the RB to survey quickly where the hole is and THEN turn it up. The Cowboys stretch plan requires the line and LB to hold their blocks longer (a longer developing play), and any penetration disrupts the play entirely. And if the OL is getting beat at the snap, there's more of a chance to hold the Dee line or LB. For the Niners, it's a quick-hitting stretch play, and it's much more effective, and less worry of an immediate hold.
Nevertheless, I think the Cowboys running game has their best chance to be formidable once the Cowboys get the lead, just like the Niners. Until then, the Cowboys should pass to set up the run, yet still use a lot of bootleg and play action.
The Niners have a unique luxury with 2 different players. They have a WR that is basically a RB who just happens to be able to catch (Deebo) and a RB that could line up in the slot as a WR like a Wes Welker or Edelman (McCaffery). Two swiss army knives in one offense is really hard to stop when they both get going. Niners loss 3 in a row when one or both of them were hobbled for a few weeks, understandably.
We never needed Henry, we need an impact LB and some o-line depth more (and maybe a rangy FS).
