On the Ravens, it seems like everyone likes Joe.
"I've never played with a guy with that much talent; I'm talking about physically," Boldin said. "I think Joe is able to make any throw on the field. Big-time throws, the deep ball, he does it all."
Flacco is known among his teammates as Joe Cool because of his calm demeanor in the huddle and the pocket.
"He doesn't flinch in any situation," wide receiver Torrey Smith said. "That's what we like about him. He's the same, whether we're doing well or bad, and you can trust a guy like that."
When it's time for business, Flacco doesn't panic. Against Denver, he moved the Ravens 77 yards in 38 seconds with the game on the line.
"You all might think we're lying about it, but I'm being so serious when I say that when we went to the huddle, no one doubted for a second that we (were) going to score," Smith said. "Did we think it was going to be a 70-yard bomb? No. But no one panicked. It was just so calm in the huddle. It was like, 'All right. Let's go do it.' And we got it done."
Recalling the drive, Flacco said, "There's no need to get all worked up over stuff like that when you know you have put all of your time, all of your effort into going out there and having fun and winning the football game. There's no need to blow it out of proportion and get overwhelmed by that kind of thing. I think when you have that mindset, it is easy to go out there and stay calm and play in that moment."
Flacco earned the Patriots' respect in last year's title game when he outplayed Brady and nearly pulled off an upset. Earlier this season, Flacco threw for 382 yards and three scores in Baltimore's 31-30 win over New England.
"He's tough to bring down, he stands in the pocket, he takes a hit, he gets up. That's a tough football player," Patriots tackle Vince Wilfork said. "When you have a quarterback like that, that's special."
Flacco's rookie contract expires after this season. Regardless of what happens Sunday — and whether he gets a long-term deal or receives Baltimore's franchise tag — he is due for a big payday in the months ahead. But Flacco has more pressing issues in mind this week.
"I'm sure it's back there somewhere, but it's not something I've really thought about or really considered," he said.
Ravens coach John Harbaugh has made his position clear: Pay the man.
"He is one of the toughest quarterbacks I have ever been around," Harbaugh said. "He's the best quarterback I've ever been around."
