Brett Favre is a Jet. No. 4 will be wearing a different color green this season. No matter how many different ways I say it to myself, I can’t quite wrap around my head how my favorite football team just acquired one of the five best quarterbacks that ever lived.Having lived in Wisconsin for two years, I know what a demi-god Favre is out there. People wear his jersey on his birthday. People took off from work when he “retired” a few months ago.I don’t know how much Favre has left, and I still think he should have gone out after his remarkable comeback season a year ago, but as bizarre as it is to imagine No. 4 in a different jersey, it’s even crazier to think of him in Jet green.
