The Tampa Bay Buccaneers have made an offer to Mike Glennon that would make him the richest backup quarterback in the NFL.

The Bucs' offer to Glennon would eclipse the deal that the Eagles gave QB Chase Daniel ($7 million per season).

Glennon has seen action in 21 career games with 18 starts for the Bucs, although he hasn't started a game in the past two seasons after the team drafted Jameis Winston.

Glennon, however, is seeking a job as a starting quarterback and plans to test free agency.
