There is a “Snyder cut” version of this write-up somewhere that is a lot more detailed, but I cannot find where the file went and have finals starting today and don’t want to spend a lot of time on this again... SO here is a condensed version.
Essentially what this boils down to is the defending SB champions adding the most “pro-ready” player on the board. The Bucs are the first team since 1979 to return every starter after winning the Super Bowl. In addition to this, the Bucs were also able to maintain OC Byron Leftwich and DC Todd Bowles on the coaching staff for at least another year.
