Can Brett Favre retire as a Viking?

I am not sure how this is to be stated. Brett Favre will retire from the NFL not a team. However since his current team is the Minnesota Vikings and if he retired today he would then retire from the NFL as a Minnesota Viking.

Now just because he is playing for the Vikings does not mean that everything he did in Green Bay is for nothing. His number, I would think if the NFL would do such a thing, the #4 would get retired NFL wide just like the #23 in the NBA.

If this is what you are worried about with the retiring of his number and such in Green Bay, that is up to the Packers to do so. If he also was able to finish this current season with the Vikings and bring them a super bowl win the Vikings could also retired his number so that the #4 could never be worn by another Viking.

However if Brett Favre retires for his final time he would retired from the NFL and not a team in general.

All my friends hate Brett Favre and what they dont get is he is 40 years old and is still throwing like he was 20!
