But Bryan Thomas recalls something else.
"You have some things that you pick up from watching him in practice," the Jets linebacker said Thursday. "This guy over the years has had a great hard count. If you watch the film, he makes a lot of guys jump offsides, and that's something you have to prepare for."
And yes, he did it in practice, too, during his lone season with the Jets.
"He did it all the time," Thomas said, and then "he'd joke around with us sometimes. That's just Favre being Favre. That's something you have to look out for."
And certainly something the Jets have seen, and heard, up close. So perhaps when they host Minnesota on Monday night, their prior experience in practicing against Favre will be a benefit.
If cornerback Darrelle Revis (hamstring) and linebacker Calvin Pace (foot) return to action, as is expected, seven of the Jets' 11 starters on defense will have played on the same team as Favre.
Favre said on a conference call that he didn't know if the Jets defense would have an advantage in preparation.
"People ask that, or people think that it would be obvious, ‘Hey, he knows them or they know Brett,' and so forth. I don't know," he said. "There are a fair amount of guys that are still there that I practiced against, but they're playing as good as anyone in the league. That's not blowing smoke.
"They give you a lot of different looks. It's a confusing 3-4. ... I don't see (the familiarity) as much of an advantage either way."
Coach Rex Ryan praised Favre, saying, "He still throws it like the old saying, ‘He can throw a strawberry through a battleship.' He's got that great arm, and he still does. He can change the arm angle. It's crazy what he does. You guys (reporters) know. You saw it up close and personal. It's still the same guy."
Maybe so, but the numbers have been un-Favre-like so far in 2010. After throwing 33 touchdown passes and only seven interceptions in his first season with the Vikings last year, Favre has two touchdown throws and six picks this season.
"I obviously need to play better (and) hope to play better," Favre said. "You've got to have a little bit of luck. There are a lot of things that go into it. ... I knew coming back it would be tougher than last year even with all the guys in place.
"I have to play better, no doubt about it."
Favre is hoping the acquisition of Randy Moss from New England on Wednesday will help him and the Vikings, who have averaged only 14.3 points through their first three games. Minnesota had a bye Sunday.
"I think, on paper, it can be a great addition. I'm excited about it," Favre said, adding with a laugh, "I would think the ball would be thrown to him. I hope he'll be a factor. ... I would love to get the ball in his hands, and at least give him the opportunity to make something happen after the catch. ... We know what he brings."
