A few random thoughts....
I suspect that the "Cardinals forced Arians out" conspiracy theorists don't believe Bowles would come to Arizona.
In retrospect... Bowles had a lot of defensive talent in 2013-2015... peak Patrick Peterson, Tyrann Matthieu, Calais Campbell, John Abraham / Dwight Freeney, Tony Jefferson, Dan Williams & Frostee Rucker, both Karlos Dansby and Daryl Washington in 2013, peak Antonio Cromartie in 2014, and a bunch of solid role players. I wonder whether he'd be as good with the talent on the current team?
Would the Buccaneers really fire a black head coach after one down year? Could they get someone better for the upcoming rebuild?
If the Buccaneers are considering trying to "keep the band together" one more year, it will surely remind Arians (and Bowles) of why he left the Cardinals when he did. No way to win with the old, thin roster remaining, and no patience for a rebuild.
