It is said that each athlete is catched up by the Father Time. But this man is an exception.when watched Brett Favre 's performance ,it's obviously the venerable veteran has turned back the clock .He has been in many teams and any NFL jersery suits him.Who can be so fantasy at the 40?
Favre presented one of his finest season to us.As a 3-time MVP winner,he contributed more than 69 percent of his passes with 24 touchdowns and only three interceptions."I don't think anyone expected him to play this well," said an NFC personnel man.He worked as a game manager on the field this season.Some of us shocked by his remarks which proclaim the Vikings as the "best team that he has ever been on."
At the same time ,the strong offensive line led by running back Adrian Peterson,the Vikings are perfect at every position.And the young pass-catches also become maturing under Favre's guidance.
