The New England Patriots and Los Angeles Chargers will have new starting quarterbacks in the 2020 NFL season after parting ways with their long-time signal callers. Because of notable offseason additions, it’s unknown who will be under center for the Miami Dolphins and Chicago Bears in Week 1.

Tom Brady signed with the Tampa Bay Buccaneers in free agency, leaving the Patriots in search of a new starter for the first time in two decades. The team didn’t draft a quarterback or sign a reliable starter, creating speculation that New England will eventually go with a signal caller that isn’t currently on the roster.

FanDuel Sportsbook gives Cam Newton +170 odds to be the Patriots’ Week 1 starter. He’s been a free agent for over a month, having been released by the Carolina Panthers. Andy Dalton, likely available with the Cincinnati Bengals selecting Joe Burrow at the top of the draft, has +900 odds to start for New England in the season opener.

Veteran backup Brian Hoyer has +550 to be the Patriots’ starter. Second-year quarterback Jarret Stidham is the odds-on favorite at -160. He attempted four passes as Brady’s backup in 2019 after New England made him a fourth-round pick.

Philip Rivers left Los Angeles for the Indianapolis Colts, ending his 16-year run with the Chargers. L.A. drafted Oregon quarterback Justin Herbert sixth overall. Tyrod Taylor is set to return for a second year on the Chargers’ roster.

Taylor is the overwhelming favorite to start for Los Angeles in Week 1 with -370 odds. Herbert has +260 odds to win the job in his first NFL game. Easton Stick, the likely No.3 quarterback, has +3200 odds.

Miami drafted Alabama’s Tua Tagovailoa fifth overall. He’s got +200 odds to be the Week 1 starter. Ryan Fitzpatrick returns after going 5-8 with the Dolphins in 2019. The veteran is favored to be the starter at -270. Josh Rosen is a +2500 long shot to open as Miami’s starter.

There’s been speculation that hip surgery could prevent Tagovailoa from playing at all in his rookie season. Fitzpatrick had 3,529 passing yards, 20 touchdowns, 13 interceptions and an 85.5 passer rating last season.

Chicago didn’t draft a quarterback or spend big money on one in free agency. Instead, the team traded for Nick Foles, creating a competition between the Super Bowl MVP and Mitchell Trubisky.

Trubisky took a step back in his third NFL season, throwing for 3,138 yards, 17 touchdowns, 10 interceptions and an 83.0 passer rating. The odds suggest he’ll lose his starting job in training camp.

FanDuel makes Foles a -150 favorite to be the Bears’ Week 1 starter. Trubisky has +117 odds to be under center when the season begins.
