Zappe appears set to operate as the No. 2 quarterback behind Jacoby Brissett, who is slated to sign a one-year, $8 million contract with the Patriots, John Keim of ESPN reports.

Zappe started New England's final six games of the 2023 season after beating out Mac Jones, who the Patriots recently traded to Jacksonville for a 2024 sixth-round draft pick, posting a 6:7 TD:INT in that span. Given that New England holds the third overall pick in the 2024 NFL Draft, in what's considered a high-end quarterback class, Zappe could end up further down the depth chart with the potential selection of rookie competition.

Lock and the Giants have reached agreement on a contract, Ian Rapoport of NFL Network reports.

Lock joins a quarterback room with Daniel Jones (knee), Tommy DeVito and Jacob Eason, after former Giant Tyrod Taylor reached an agreement with the Jets on Monday. It's a situation that strongly favors Lock for the No. 2 QB job, though the Giants may not be done making additions/subtractions to the group, with the upcoming NFL Draft offering potential to add a long-term replacement for Jones (who is rehabbing an ACL tear). Lock made four appearances for Seattle in 2023, including two starts, completing 48 of 76 passes (63.2 percent) for 543 yards (7.1 YPA), three touchdowns and three interceptions. He never panned out as a starter in Denver after going in the second round of the 2019 NFL Draft, but Lock at least looks like the part of a high-end backup after his moderately successful cameo with the Seahawks last year.

The Browns are reportedly closing in on a deal to acquire Winston, Jake Trotter of ESPN reports.

Winston, who is still technically under contract with the Saints, would be in line to replace Joe Flacco as Cleveland's No. 2 quarterback behind Deshaun Watson. The Browns also roster Dorian Thompson-Robinson, but Winston -- the first overall pick in the 2015 NFL Draft -- has ample starting experience, and Watson is coming off an injury-shortened 2023 campaign.

Mariota is in line to sign a one-year contract with the Commanders, Adam Schefter of ESPN reports.

After spending a year as Jalen Hurts' backup in Philadelphia, the 30-year-old Mariota will join a Washington team that has Sam Howell under contract for two more years and owns the No. 2 overall pick in the 2024 NFL Draft. This signing would seem to hint at a desire to either trade Howell or move down in the draft. In any case, Mariota seems like a good fit with new Commanders offensive coordinator Kliff Kingsbury, who tends to rely heavily on shotgun formations and avoid play calls with slow-developing routes. Mariota's one-year contract reportedly has a base value of $6 million and can go up to $10 million with incentives.

Ridder figures to be relegated to a backup role with the Falcons set to sign Kirk Cousins, per the team's official website.

The 2022 third-round pick has won eight of his 17 NFL starts while throwing 14 touchdown passes and 12 interceptions. He's completed 64.0 percent of his passes for 7.0 YPA, but with a higher-than-average sack rate (7.4 percent) and nine lost fumbles. Overall, Ridder has the same number of turnovers (19) as combined passing and rushing TDs in the NFL. The Falcons likely will release Taylor Heinicke after their agreement with Cousins becomes official.

Rudolph has free-agent interest from multiple teams, according to Mike Garafolo of NFL Network.

The Steelers presumably aren't one of those teams, considering they recently reached an agreement with QB Russell Wilson and have 2022 first-round pick Kenny Pickett under contract for at least two more years. Rudolph stepped in for an injured Pickett at the end of 2023 and continued to start once Pickett was healthy, leading Pittsburgh to three straight wins at the end of the regular season before a loss at Buffalo in the first round of the playoffs. The 2018 third-round pick went 8-4-1 as a starter in his six years with the Steelers, completing 63.5 percent of his passes for 6.7 YPA with 19 touchdowns and 11 interceptions (on 458 career pass attempts). Rudolph won't add much on the ground (93 career rushing yards, zero TDs), but his career passing numbers are at least toward the high end of what's expected for a backup quarterback, with other positives including a low sack rate (4.6 percent) and just one lost fumble.

Darnold agreed to terms on a one-year, $10 million contract with the Vikings on Monday, Ian Rapoport of NFL Network reports.

Darnold spent the 2023 campaign as Brock Purdy's backup in San Francisco, but he now will join his former teammate and current Vikings quarterback coach Josh McCown in Minnesota. With Kirk Cousins en route to Atlanta, Darnold becomes the de facto No. 1 option under center with his new team. Darnold completed 16 of 26 passes for 189 yards and one touchdown while adding another 19 yards and a trip to the end zone on seven carries in his only start for the 49ers last season. It remains to be seen if Minnesota will draft or bring in competition for Darnold, as the journeyman signal-caller could be viewed either as a bridge to a younger quarterback or potential option for the future.

Taylor has agreed on terms on a two-year, $18 million deal with the Jets, Tom Pelissero of NFL Network reports.

Taylor is staying in New York but will sport a different jersey. The journeyman signal-caller accumulated 1,399 yards and six touchdowns through the air across 14 games (five starts) during his two-year stint with the Giants. With 58 career starts under his belt, he's a safe veteran choice to back up Aaron Rodgers (Achilles), as the Jets were determined to improve in that department following the 2023 season.

Brissett has agreed to terms on a one-year, $8 million contract with New England, Jeremy Fowler of ESPN.com reports.

It remains to be seen what the Patriots choose to do with their No. 3 selection in this year's draft, but Brissett is now the No. 1 option under center with New England one day removed from dealing Mac Jones to the Jaguars. The journeyman quarterback started his career with the Pats in 2016 and actually started two games in place of a suspended Tom Brady. He then spent his next four seasons with the Colts, both as a backup and starter before subsequently spending one year each with the Dolphins, Browns and Commanders. If the team does decide to draft a quarterback, Brissett still could start while the team develops someone behind him or use him as a top-tier backup option.

Minshew has agreed to a two-year deal with the Raiders, Tom Pelissero of NFL Network reports.

Per Pelissero, Minshew's deal is for $25 million and includes $15 million fully guaranteed. Given those reported numbers, Minshew should have a chance to compete with Aidan O'Connell for the Raiders' starting QB job. Minshew -- who turns 28 in May -- recorded 3,305 passing yards to go along with 15 TDs and nine picks in 17 regular-season games (13 starts) with the Colts in 2023. With Minshew on the way out, 2023 first-rounder Anthony Richardson, who is bouncing back from a shoulder injury, is poised to reclaim Indy's starting signal-caller assignment this coming season.
