I do think Todd Bowles can be a good coach, though. The year he had Fitzpatrick, Brandon Marshall, and Eric Decker to work with on offense, the Jets went 10-6, and only barely missed the playoffs. The following year, Fitz could not stop throwing interceptions and they started something like 1-5. Also it was becoming apparent that McCaggnan's GM moves were not good ones. And then the third and final year of Bowles' tenure was Sam Darnold's rookie year. Enough said about that.
Bowles is no Arians, but he's had HC experience, some of it good, is already part of the org, and holds one of the most qualified resumes of assistant coaches in the league. Tampa Bay is 24-9 over the last two years and a sure shot to win the division again this year. And Arians is departing on his own terms. This is not a blow it up and build from scratch situation, especially now that Brady is back. If I were in charge of the Bucs, I'd be wanting to retain continuity as much as possible. This is no way a "rule" hiring. Bowles is the next man up in the organization.
Sure, it's by no means a sexy hiring. But that's something I've noticed from fans of winning teams, as a fan of a losing one. They are just like us, constantly complaining when their teams make smart, logical, un-sexy moves, undervaluing the continuity that makes their teams great.
