Bridgewater is competing for the starting job in Denver with Drew Lock. But should he lose that competition, he’ll immediately become a top-end backup. Essentially, that is his ceiling–a replaceable, backup-caliber quarterback.
As a defensive guy, Zimmer seems to notably loathe two positions–quarterbacks and kickers. The exception to that rule was Bridgewater when who he openly professed love for and then concern for as he worked his way back from a 2016 knee injury as a Viking. If asked today, Zimmer would certainly continue to profess his platonic affection for his former quarterback.
As a noted Bridgewater detractor practically from the start, which leaves me in the clear minority for those Vikings followers who saw him (and still see him) through purple-colored glasses, the idea of his return to the Vikings makes me yawn (or nauseous, I haven’t totally decided. Maybe it’s both). But he has experience, and he gets credited for being a “winner” (as much as wins are not a great quarterback stat, and intangibles don’t cover a lack of talent). He would also not be a divisive presence in the locker room, in regard to the vaccine or anything else, which looks to be very important for the Vikings at this point.
