May do this a few more times, Gary Gibson (#71).
After releasing John McCargo, the Tampa Bay Buccaneers acted quickly to add some extra depth at defensive tackle by signing eighth-year DT Gary Gibson according to Adam Caplan. The defensive tackle spent the past three years with the St. Louis Rams after barely earning any playing time with the Carolina Panthers in his first four years in the NFL. Last year was his most productive season, as the 6'3", 312 lbs. tackle notched the first three sacks of his career.
Gary Gibson was originally an undrafted free agent out of Rutgers, and he played under current Buccaneers head coach Greg Schiano in college, which would explain why the Bucs went after him. A cursory look at some of his games shows a defensive tackle who can hold his ground in the run game, plays with good leverage and effort, but doesn't look very disruptive. Watching him, the words 'Roy Miller with better technique' come to mind.
Gibson should compete for a backup job at nose tackle, or as a two-down run stopper at three-technique. As noted by Adam Caplan, he signed a two-year deal worth $2 million with $400,000 guaranteed.
