The Tampa Bay Buccaneers made wholesale changes to their defensive line during the 2018 offseason and then funneled a lot of draft resources into reloading in the secondary. The Buccaneers hope they will be much more invasive up front and would like to get more big plays out of the back end of their defense. At the very least, we know those two units will be different in 2018.
The meat in that defensive sandwich, the middle level, is the linebackers, and in contrast that crew has seen very little change since the end of last season.
