They’ll have the cap space next year
While the Buccaneers are currently backed up against the wall of the salary cap in 2019 with only about $3 million in space, next year will be a much different story in Tampa Bay. According to Spotrac, the Buccaneers will have over $26 million in flexibility to spend.
Williams’ contract would eat up over half of that flexibility, and the Buccaneers will have to consider new deals for Carl Nassib, Shaquil Barrett, Deone Bucannon, nad other as well. However there are potential outs of deals such as Ryan Jensen and Jason Pierre-Paul, who carry a cap hit of a combined $22.5 million.
Needless to say, the Buccaneers will once again have money to spend, so adding Williams would not put the Buccaneers in any sort of financial bind. They would, however, have to scrap to clear space this year in order to bring him in.
Some options to explore to clear space could be cutting William Gholston and Evan Smith, and/or trading Cameron Brate with the emergence of O.J. Howard. If they can figure out a way to afford Williams in 2019, then there will be no stress beyond this year with money.
