Aside from DA is anyone really happy with Kubiak's play calling?

You're judging him based on an largely incomplete roster. And by a HC who is a poor leader. KK is in a no win situation here. They haven't had anything close to a reasonably healthy offense since week 2.

Also, if players don't execute the plays called...

I am judging on watching Kamara run through the middle for no yards and the sweep to the short side for no yards plays we see over, and over, and over again. I'm judging him on putting Rattler under center rather than on shotgun. I'm judging him on not modifying the protection.

He's as guilty as Allen. Allen has an incomplete roster too.
