EDEN PRAIRIE, Minn. — Brett Favre is back in the building. The 40-year-old quarterback returned to Minnesota on Tuesday, arriving in a private jet trimmed in the Vikings' purple and gold with three teammates who were sent to Hattiesburg, Miss., to bring him back for one more shot at a Super Bowl. This time around, Favre got a ride to Vikings headquarters from kicker and close friend Ryan Longwell – last year, when he joined Minnesota, head coach Brad Childress was at the wheel.
