Focusing on what a team is going to do without having to formulate a play to stop it is easy. These announcers and their teams get ton of footage probably from the all-22 and they have almost a week to get their notes together to call a game. DC or LB will have a day or 2 to study and make preparations for the game.
He wasa QB in the NFL and he was a student of the game. He can see tendencies and probability. Its one thing to call it out on the air its another to gameplan against it. Like I said he gets to study tape for almost a week before the game so you can get into the minutiae since all you are is looking at teams and their tendencies. Dissecting tape for 5-6 days gives you more info than a guy that has to watch film, devise a scheme to beat it, then make sure your players execute and hope you do not need to revisit tape before game day. Being a coach has too many other responsibilities that need to be done besides watch tape.
