According to Jason LaCanfora, Jonathan Crompton has just signed a three-year deal with the Tampa Bay Buccaneers. The former Tennessee Volunteer was a fifth-round draft pick for the San Diego Chargers in 2010, but spent most of the 2010 season on the Patriots' practice squad. The Patriots released him a couple of days ago.
It's likely that Crompton will simply compete for the backup job in training camp. The Bucs have Josh Johnson and Rudy Carpenter under contract, as well as former Boise State backup Mike Coughlin. Johnson seems entrenched as the main backup, while Coughlin is only in town as a training camp arm. Rudy Carpenter is the player whose job is threatened by the addition of Crompton. While Carpenter has experience in the Bucs' offensive system, he has very limited arm strength. Crompton has a lot of talent, but was inaccurate and inconsistent throughout his college career.
With Josh Johnson scheduled to be a free agent after 2011 and having made clear his desire to be a starter in the future, he is unlikely to remain a Buccaneer in the long term. Crompton could be the future backup if Johnson does indeed leave. Crompton also has the talent to turn into a solid starter, and if he develops well he could be traded for a draft pick at some point in the future.
Of course, the fact that both the Chargers and the Patriots released him may say something about his development as a quarterback.
