I'm not saying they weren't fouls, but it was a marked change from the way things have been called in the playoffs this year. Hard to adjust if all of a sudden things get called differently. And the Chiefs, in the games I've seen them, have been playing that style for a couple years.
That being said, IMO, it ultimately made no difference. The MVP of this game was the Bucs D-line, who totally dominated the game, with the Bucs O-line a close second.
