Fran Tarkenton, who previously has expressed his loathing over Brett Favre's inability to make a decision, spoke out again Wednesday, a day after Favre decided to sign with the Minnesota Vikings.

"I really have no interest in what Brett Favre does. He kind of lost me a few years ago by retiring and unretiring and here and there," Tarkenton said on "The Opening Drive" on Sirius NFL Radio.

"I asked a few friends here, maybe 10 or 12 people we were out with last night. I said, 'What do you think about Brett Favre going back to the Vikings?' You know who cared? Nobody. It's good news for you guys. It's good news for television and so forth but the last time I heard ... football was a team sport, isn't it? It's not just about the quarterback."

Tarkenton was later questioned during ESPN's "Outside the Lines" about Favre's right to pursue whatever he needed to pursue to keep on going.

"We have responsibilities we're just not athletes that are in it all for ourself, football, is it not a team game? Isn't it all about team ... and here comes Brett Favre riding in on his white horse, doesn't go to training camp, doesn't come to offseason workouts and he's gonna come on his white horse and bond with all these players."

Favre, who first retired in March 2008, came out of retirement and forced the Green Bay Packers -- with whom he had starred for 16 years -- to trade him to the New York Jets in August when the Packers declined to accept his unretirement.

He played one season for the Jets, then retired again in February.

But rumors started bubbling again in May that Favre wasn't fully committed to retiring. Vikings coach Brad Childress communicated regularly with Favre. And Tarkenton -- a Hall of Famer who spent five seasons with the New York Giants, but is remembered for his 13 seasons with the Vikings -- made clear he was disgusted by the team's flirtation with Favre.

"I think he has been a great flamboyant quarterback, but he has made more stupid plays than any great quarterback that I've ever seen. Look at his final game in a Packers uniform. He blew that game [NFC championship] against the Giants," Tarkenton said in late May on KFAN-1130 in the Twin Cities.

At first, Favre said he would remain retired. Then he wasn't sure. He said he would let the Vikings know by July 30. Then he decided he'd stay retired. Then on Tuesday, he flew to Minnesota and signed a two-year deal worth $25 million.
