I was thinking similarly watching the Rams game last night. They have a lot of speed, a nice QB, and an elite talent at RB. They may have a "Good" Oline, I'm not good enough to evaluate NFL teams down to that granular detail, but I don't think their OLine is "Special" or "Elite" level. They spread the ball around, don't have an AJ Green, Antonio Brown, Calvin Johnson, or Randy Moss on that roster. Shoot, they made Jared freeking Cook look like a Hall of Famer last night. Look how many carries their WR's had? I think it was at least 8-10 rushing attempts from their WR's.
I've been one who all along has said that our offense is "fine", there are open WR's to throw to if we just had a competent QB who could place the ball accurately and, ON TIME. This is still true.
That being said, we can do better. I hate this "motion" conversation because it makes it seem as though just putting someone in motion on every play will solve all our ills. BUT, we can do much, much better. There is no reason CJR and CMR and Thomas Brown and Dugans shouldn't be spending serious time in the offseason and even during the season visiting the Sean McVay's, Jay Gruden's, Josh McDaniel's, Doug Pederson's and Andy Reid's of the world, watching NFL football games, and stealing their plays and concepts, at a minimum. That shovel pass, sweep motion TD from Todd Gurley last night (I think it was the first TD of the game) was a thing of beauty. The play almost completely takes the OLine out of the equation and relies on the positioning and blocking of the WR's, which is something we actually excel at.
Unless things change, they are going to stay the same.
