Bucs want Mike Glennon back, but know he will be in demand as free agent

The Tampa Bay Buccaneers have offered a contract extension to backup quarterback Mike Glennon, but they expect Glennon to test the market when he becomes an unrestricted free agent next week.

As of March 1, the Bucs have about $68 million in salary-cap space, fourth-most in the NFL, but Glennon would love an opportunity to start, and the team has to address needs at other positions too. They won't deviate from their own set price range.

“We’d love to have Mike back in a perfect scenario," general manager Jason Licht said to reporters at the NFL combine Wednesday. "It’s going to depend on, I think for him, he’s going to have some opportunities, where it is, what the landscape is there, how good of a chance he has to start there, but we’d love to have him back.”

Interest in Glennon may intensify given the news that the New England Patriots are not expected to trade backup Jimmy Garoppolo. League sources told ESPN's Adam Schefter that with Tom Brady turning 40, the Patriots intend to keep him for 2017 and possibly beyond. The Washington Redskins also placed an exclusive franchise tag on Kirk Cousins.

Several NFL teams are in need of a starting quarterback this offseason, including the Cleveland Browns, Chicago Bears, San Francisco 49ers and New York Jets. Many draft experts feel that it's a weak quarterback class in the draft, however.

Glennon, 27, has served as the backup to Jameis Winston the past two seasons after Winston was selected first overall in the 2015 NFL draft. A former fourth-round draft pick, Glennon has seen action in 21 career games with 18 starts in his first two seasons, where he went 5-13 as a starter. He's thrown for 30 touchdowns with 15 interceptions and has completed 59.4 percent of his passes as a pro.

The Bucs have been preparing for Glennon's departure for some time, which is why they kept third-string quarterback Ryan Griffin, who was not eligible for the practice squad, on the active roster last year, believing his system familiarity could elevate him to the No. 2 spot in 2017. Griffin has been with the Bucs for two years now and will become a restricted free agent when the new league year begins.

The Bucs also signed Sean Renfree, who played under head coach Dirk Koetter in Atlanta from 2014-15.
