This has nothing to do with the headset signals but that Gronk/Chandler lined up on the same side at the goal line seems unstoppable. You can't put cover guys on them cause you can just run the ball. You can't put a LB on Gronk either in that spot. That's like having a PF try to guard LeBron.
That just seems unstoppable with 2 guys that good at blocking. It'll be interesting to see if teams can comeup with anything.
