One thing is for sure after today: the Green Bay Packers are going to need a new identity.

After being with the Packers for 16 years, future Hall of Fame quarterback Brett Favre retired Monday. The move was confirmed by Favre's agent, Bus Cook, Tuesday morning.

Every year, Favre has been the highlight of many discussions in the NFL -- from his consecutive starts streak, his playoff-leading seasons, to his unrealistic performances under adversity. Favre's four-touchdown performance against the Oakland Raiders nearly right after his father passed away will go down as one of the greatest moments in league history.

Now, the Packers' organization will be forced to move on with a new face: Aaron Rodgers. Although it's a shame for many Packers fans to see Favre retire, if there were ever a time for him to do it, this was it. The Packers are coming off of a tremendous season in which their defense reached new heights. They also established Greg Jennings as a top-caliber receiver, and saw Ryan Grant emerge from the back of the line. Instead of leaving the Packers for dead when they were down and beat, he has left them when they still have an opportunity to succeed next season under Rodgers.

One note that will surely be asked of Favre is whether or not he would have indeed returned for another season or two if the Packers had signed wide receiver Randy Moss to a deal. ESPN.com reported last week that Favre and Moss had spoken, and that Favre told Moss that he'd return if Moss signed with the Packers. Reports indicate that Green Bay showed no interest in Moss, and Favre's retirement came shortly after it was announced that Moss re-signed with the Patriots.

There will be a lot of different opinions about Favre. Packers fans will adore everything he has done (beyond Packer fans though, you have to wonder if John Madden feels the worst of all). Some fans around the league will feel the same. Other fans around the league will be thrilled that he retired -- whether it be because they are rivals of the Packers, or that they were sick of Favre delaying his decisions (regarding retirement).
