Tom Brady began preparation on Monday for Sunday's AFC Championship Game against the Ravens. Brady called Baltimore "the best team we've faced all year." "There's no one that's going to overlook a team like that. It would be impossible to do," Brady said in his weekly interview on WEEI in Boston. "They present a ton of challenges in all three phases of the game. You watch them yesterday, they're physical, they're tough, they can cover. They've got some of the best players in the history of the NFL at their position, in (Terrell) Suggs and Ray Lewis and Ed Reed and Haloti Ngata. You've got phenomenal players there. "We've really got our work cut out for us. We'll be excited about the challenge. We'll use the week to prepare like we always do, and really try to be at our best -- hopefully be better than we were this past Saturday night." Back in 2009, the Ravens came into Gillette Stadium in the wild card round of the playoffs and embarrassed the Patriots, 33-14. "This is nothing about '09 or '10. This is nothing about last week or last season or last month or 10 years ago. It's about this week," Brady said. "The clock's ticking. And every second that goes by, we're one second closer to getting to that game. We've got to use our time wisely, to repair, get our rest, and be ready to go out and face our biggest challenge of the season."
