Lamar had a wonderlic score of 13. He is not a bright fellow by any means. It’s partially why he struggled against the patriots and Steelers defenses.
The bills should disguise their coverages, blitzes, and schemes pre snap. Get Lamar to second guess what he’s doing. Hell, get him to think for 3 long seconds in the pocket, but just make sure you can contain when he does decide to finally scramble.
