Hmm...this is probably a stupid question. But, can ya line Hill up next to Carr, then before the snap, have Carr shift left/right, and be replaced at QB with Hill? Put the defense in a spot.
You can, it’s kind of like when you put both of them in the huddle and then put Carr out wide to and Hill at QB.
But I think you have to question whether we are better off just committing to having 10 blockers with Hill and telling opposing defenses “you know what we are going to do, just try and stop this” with the threat of that 20% chance this is actually a passing play being the “keep them honest” step.
