Technically, this probably is a throwback jersey, even if it is new.

Brett Favre's Vikings jersey was the top seller on the NFL's merchandise Web site. His purple No. 4 was only available for the last two weeks of that timeframe, too.

Fans typically flock to new products, and Michael Vick's Philadelphia jersey has been a hot commodity as well: His No. 7 in Eagles green ranked No. 4 on the list behind Favre, Jay Cutler and Troy Polamalu.

Favre didn't express much surprise Wednesday when the popularity of his jersey was pointed out. He said friends and family have asked him if he can get one for them, but that all he has are the ones he wears in the games.

Favre then retired and un-retired again, making the jersey a collectible, too.
