Haven't we seen this before? Brett Favre has come out of retirement yet again and is now a Minnesota Viking, setting the stage for intense games against his former team, the Green Bay Packers. The signing also makes the Vikings, who already have a fierce running game and defense, early contenders to go deep into the playoffs. The 39-year-old quarterback's arrival in Minnesota was so hotly anticipated that a local news helicopter was actually filming his arrival at training camp. ESPN has reported that he will start in this week's preseason game. Only three weeks ago, Favre had told the Vikings' coach he would remain retired.
