Flash back to a sunny afternoon in Eden Prairie, four years ago at the end of August, and pretend it all had gone differently.
Pretend Teddy Bridgewater's left knee had held firm as he dropped back to pass early in the Vikings' final preseason practice. Pretend he'd gone into his third season healthy and led the Vikings out of the tunnel for the Sunday night opener against the Packers at the new U.S. Bank Stadium.
Would Bridgewater have stayed healthy to lead a team that started the 2016 season with five consecutive victories? Would he have taken the 2017 Vikings on a ride to the NFC Championship Game? Would he still be here now, firmly entrenched as the starter in the middle of his second contract?
Or would his knee, as some who studied Bridgewater believe, have eventually collapsed at a later date?
It's all the stuff of conjecture now, as the quarterback with whom coach Mike Zimmer thought he'd spend the rest of his career returns to Minnesota as an opponent for the first time, trying to help the Panthers keep their faint playoff hopes alive while dealing a body blow to the Vikings' own chances.
Carolina is Bridgewater's third team since he left Minnesota after the 2017 season, and the first for whom he's been named the starter since he tore multiple ligaments and dislocated his left knee Aug. 30, 2016, in what still ranks as one of the more gruesome and bizarre injuries in recent pro football history.
But even as Bridgewater has gone from franchise fixture to what-could-have-been story, the impression he made on the Vikings seems to transcend all of it.
"I'm pretty certain in making this statement: In the 10 years I've been here, he has to be the most likable player that we've had in the locker room," tight end Kyle Rudolph said. "I mean, you just talk to people in the front office, coaching staff, players that played with him, workers in the cafeteria: Everyone loved Teddy. You loved his energy and positivity that he brought every day, his work ethic that he brought every day."
