It's funny just how many people can do a complete 180 on negative, defensive boxing when they like the guy doing it. Fury was the better boxer for most of the fight, but there were several rounds that he left very close because of his very low workrate and lack of commitment to sitting down on his offense. When you get floored hard twice, you're absolutely playing with fire by mounting such little offense even if you're making your opponent miss a lot.
I mean, I hate to appeal to punch stats as they're massively flawed, but there were 8 rounds out of the 10 where Fury wasn't floored which had them landing within 2 punches of each other, 3 within 1 punch of each other (and there were 3 where Wilder allegedly outlanded Fury). If you want to disregard their landing stats (which is reasonable as it's a fairly laughable process), you can look at the raw thrown numbers which do tend to be fairly reliable. Fury threw 30 or fewer punches in 9 of 12 rounds. When rounds are that close and offensive output is so low, it's pretty rare that fights can be called a robbery if one guy wins 3 of the 10 (which would precipitate a draw).
