He threw 33 touchdowns and a career-low seven interceptions in part because he made a quick connection with many of his receivers and also because he was put in a position to succeed.
That hasn't been the case in 2010.
"I know I've got to err a little more with caution on some of these decisions," Favre said. "History has shown with me that when we're struggling a little bit, I try to press the issue and try to make something happen. I think that's what has made me the quarterback I am and has benefitted me throughout my career. But it's also hurt me. It's hard to be patient and try to get the puzzle pieced together because we're doing it as we play. Next week, it could be different. The following week, it could be different. Who knows?"
Favre has four interceptions and one touchdown and the Vikings are 0-2 in part because the veteran is pressing and that chemistry he built last season is long gone.
Favre's issues include a receiving corps that has lost Sidney Rice for half the season after hip surgery and has two newcomers in Greg Camarillo and Hank Baskett, who arrived on Wednesday after being let go by Philadelphia on Tuesday.
Rice was Favre's favorite target in 2009 and could often use his 6-4 frame to go up and get passes. Favre had no one like that in his first two games, although Baskett is listed at 6-3 and could help. With only three catches in two games, Bernard Berrian has been as productive as a well-paid No. 1 receiver should be.
"Bernard has not hit on all cylinders like Sidney and I did," Favre said. "But very few times in my career have I just clicked with a guy like that. What did he have? 90-plus catches? There's no doubt Bernard's a different player from Sidney. But so is Percy. Percy, Bernard, Sidney, they're all capable in their own way of making those types of plays."
The question is when will Favre start to get on the same page as some of his new receivers and when will he stop pressing?
"If I sat here and told you that I knew exactly what we're doing right now I'd be lying," Favre said. "A lot of work is left and it will be an ongoing process until we have our unit how we want to go about things and we're not there yet."
