It's the same with Lamar. When he doesn't run, or when he's hemmed in like he was vs. KC, he's like 50% effective at best.
I think Allen needs to run a bit more on breakdowns. Last night he got away from pressure, rolled right a few times and instead of taking the easy 8-10 and going out of bounds...he threw one low pass and one high pass. I also think his running gets him a better feel for the game.
But overall I don't like the designed runs...only the ones he creates after a play breaks down.
