When I was a kid, the Colts were property of Baltimore, not Indianapolis. Until traveling the Mayflower(s) to a promising new land, the Colts were no more relevant than, say, the Atlanta Falcons or San Diego Chargers.

The Green Bay Packers ... now that’s a whole other ’70s show.

Over time, Indianapolis has become my second-favorite NFL franchise — a close second, at that. However, if the skies above ever open up and deliver a Colts-Packers Super Bowl, it’s green and gold all the way.

I’ve been spoon-fed equal doses of bad (a record of 147-203-9 between Lombardi and Holmgren) and good (13 consecutive non-losing seasons from 1992-2004), so, yes, recent rumblings about Brett Favre have been of interest.

Difficult as this is to say, Brett, please stay retired.

Again, this from a GB lifer who remembers the twilight of Bart Starr’s playing career, running backs named Barty Smith and Terdell Middleton, Jim Del Gaizo’s left-handed bullet passes and two home games a season played a two-hour car ride to the south in Milwaukee.

For your body’s sake, for your legacy’s sake, stay retired. For your family’s sake, stay retired.

Favre is hands-down the best quarterback the franchise has produced and one of its five all-time greatest players. He is an iconic figure in Wisconsin and nationwide after seasons of thrilling fans with his grit and improvisational masterpieces.

But now is the time, the perfect time, to call it a career. Favre did so in teary-eyed fashion following his storybook 2007 season, so we know he’s capable.

Clearly, Favre’s football-playing instincts have kicked into high gear with Green Bay’s first training camp practice session scheduled for July 28. Word is he’s thinking of coming back, and there is little doubt Favre is physically and mentally capable of a 3,000-yard season given the offensive weaponry surrounding him.

But it’s simply not going to get better than last season when the 38-year-old signal-caller directed the Pack to a 13-3 regular-season record and a berth in the NFC Championship Game.

Favre needs to sit back, relax and pull for the Pack from his home in Mississippi.

Green Bay’s offense belongs to Aaron Rodgers now. Though most of us wouldn’t know Rodgers if he was standing next to us in line at a McDonald’s, it’s his time to lose the floaties and either sink or swim.

Packers fans might be pleasantly surprised. Then again Rodgers, 24, always will have one strike against him in that he didn’t come into this world named Brett Favre.

Seriously. It could be the year 2019 and in Packer land the possibility of a Favre comeback might actually have people stoked.
