I've always loved when our hand wasn't tipped pre-snap due to which RB was in the game. There have been several years where just as an average fan you could guess run/pass based on which RB was in there. But when PT was on the field it could be anything. With AK & Ingram you couldn't tell what was coming.
With Drew it didn't really matter though. Everyone knew what SP's offense was about. It was no big secret but it was executed so well that you couldn't stop it. Going forward with Winston though, it would be nice if defenses didn't get to sell out one way or the other. Just that split second of hesitation can make a difference. Force defenses to think a little to slow them down.
