CB/S Walter Thurmond
Signed from the Seattle Seahawks this offseason, Thurmond was moved to safety and has turned into one of the better players in the NFL at that position. Pro Football Focus ranked him as the fifth-best safety in the NFL, and he's turned into a veritable ballhawk at safety -- exactly the kind of player the Bucs could use, as they've struggled to get many splash plays out of their safety position for years on end. Thurmond has three interceptions a sack and a forced fumble this year, as well as 30 tackles and four passes defensed. He'd look pretty good for the Bucs defense.
LB/DE Brandon Graham
Brandon Graham hit the free agent market this offseason, but the Bucs didn't really pursue him. Maybe they should have: the fifth-year player has 4.5 sacks this year and has been reasonably productive. Meanwhile, the Bucs are starting an undrafted rookie at right end due to injuries and a general lack of quality and depth. Think they could have used a quality pass rusher?
DE Fletcher Cox
With Gerald McCoy in town, Cox doesn't really fill a need given that he's more of an interior pass rusher -- but it's hard to overlook how good he's been. The 3-4 DE has 5.5 sacks, and has the second-highest grade among 3-4 defensive ends by PFF's reckoning.
TE Zach Ertz
Austin Seferian-Jenkins is talented, but all that talent doesn't do all that much when he's not actually getting on the field. Meanwhile, Ertz has 382 receiving yards on 36 catches and is ranked fifth among all NFL tight ends by Pro Football Focus. He'd give Jameis Winston a reliable target over the middle of the field, something the Bucs could very much use right now.
