It's an intriguing matchup. You have the established coach and quarterback against two of the top newcomers in Ravens coach John Harbaugh and second-year quarterback Joe Flacco. The Ravens are exciting to watch because they have more balance now than at any other time in their brief history. They have multiple weapons on offense, and finally a quarterback who is the real deal in Flacco, who has the strong football IQ to match his arm strength. The Ravens are also strong up front on both sides of the ball, and they have one of the best front sevens in the NFL.
But I don't like how the Ravens' secondary matches up with New England's receivers. They don't have anyone to physically challenge Randy Moss, and they don't have a nickel back or linebacker who can run with Wes Welker in the slot. It's easy to say the Ravens have to pressure Brady, but I think Belichick made some corrections after the Jets pounded Brady with blitzes two weeks ago. The best bet for the Ravens is to unleash their own power running game, and keep Brady off the field.
Anyway, it should be a good game. These are two quality football teams with two good coaches.
