I'm biased, but that was an awful Super Bowl. I have no idea what the refs were watching. All the injuries on the Chiefs offensive line finally caught up to them at the worst time. Even then Mahomes had two touchdown passes dropped that hit his receivers in the facemask. Crazy.
The Bucs' defense does deserve a lot of credit for what it did, but I think you(and the announcers) are ultimately right: the game plan was apparently "keep picking on the fifth-string linemen, and take advantage of Mahomes' turf toe." Can't knock it, it worked. What I can knock is some of those calls; the early ones especially felt rinky-dink.
