IMO, all Caldwell, or any other coach for that matter, can do, is put his players in the best possible position to win the game. We haven't even seen a single call from him so far, so it's somewhat pointless to debate what he will or won't be able to do. What I believe is that he will do a better job than Cam Cameron when it comes to making in game adjustments, using more of the play book and hopefully more of the middle of the field, sensing who is hot and who is not, taking input from the players, and forming a better working relationship with Joe Flacco. If any or all of those things come to be, then Caldwell will be a marked improvement over Cameron.
