I was watching a few streams - bounced back and forth. They both cut out at the end of 5 and a minute into 6. When they came back, the British broadcast was talking like Fury was up 4-1...which I thought was nuts and clearly bias. Watching without commentary for the early rounds, I thought Wilder was up 3-2 with them all being pretty close rounds.
Then I go over to the Mauro broadcast and they, too, were going crazy saying Fury was up crazy rounds. Fury was rattling off mid-round win after win, but even after the first knockdown 10-8 round for Wilder, I thought we were real close. Neither guy was really controlling rounds. Wilder was erratic and Fury wasn't really doing any damage.
I don't see any real scenario where Wilder won the fight by the significant margin the one judge had it as, but feel the draw was very fair.
