Richard Sherman’s an idiot for telling the whole world about it, now Manning will change how he communicates, and so will other teams.
I don’t see him telling anybody anything they don’t already know. Peyton tends to be very predictable, he has a handful of passes he really likes and most of his pre-snap adjustments are figuring out which one will be open and getting the rest of the team on page. It’s how NO got the pick six on him his last trip to the big game, they gave him a look he frequently responds to by throwing to the left side flat, and at snap they backed out of the look jumped the route and ran it in. You can learn a lot with 2 weeks of tape review.
