At first the Dolphins seem like a logical choice. However, Ryan Fitzpatrick is likely to return, Josh Rosen is still under contract, and the team is expected to add a rookie passer at some point as well. Ultimately, I think they look elsewhere.
The only quarterback the Bills have under contract for 2020 other than starter Josh Allen is Matt Barkley. They could definitely stand to upgrade that backup spot, especially with as many hits as Allen takes. But Buffalo gets cold, and I’m not sure the idea of being a backup in Buffalo, New York, is something that appeals to Marcus.
The Steelers are in an awkward position. Ben Roethlisberger has given every indication he plans on returning in 2020, but he’ll be 38 by Week 1 and is coming off a serious injury. And after seeing Devlin Hodges and Mason Rudolph attempt to play quarterback, a contingency plan is definitely needed. I believe the Steelers would be better off with a mid-round rookie to develop, though.
Denver is an interesting spot. John Elway loves switching up the quarterback room, but he seems to love Drew Lock. Lock looked good enough this year, and I don’t see a need for another starting-caliber quarterback right now to possibly stunt Lock’s development.
The Bengals were absolutely terrible in 2019, and the Red Rifle era seems to be over. However, the Bengals are widely expected to take Joe Burrow with the first pick, and typically if you draft a quarterback in the first round, he’s going to get every chance to play.
Now, lets get on to the 5 teams I believe are realistic destinations for Marcus Mariota.
