Well, no doubt he is good, IMO, the best fighter in heavyweight division before was Deontay Wilder, he had KO wins in most of his fights, there's only one win with no KO which was against "Bermane Stiverne", but after that fight, it was all KO or TKO wins before he lose against Fury.
In the first fight when the fight ended a draw, Wilder knock out Fury and thought the fight was over, but Fury stand up and continue the fight as if nothing happen. The reason why Fury won is simple, he can talk the power of Wilder so he can be aggressive in the fight.
Look at the rematch, Wilder was surprised because Fury has become the aggressive and Wilder was not used to that in any fight since he was always the aggressor.
Deontay Wilder definitely wasn't the best fighter in the division at any point in his career, and not he's looking to hang onto his career. There was a contract setup for a trilogy fight, but it seems that Wilder might have pulled out of that. He came up with excuse after excuse after losing, and the way he threw his coach under the bus didn't sit right with me.
Its true, that hes got dynamite in his hands, but hes not a particularly good boxer. In fact, most of his fights hes actually being outboxed, and sometimes by men who are aging (Ortiz). However, it takes him one punch to turn the lights off, and that's what he continuously did. Although, he didn't particularly fight top fighters. He fought mostly journeymen, and aging once was fighters.
Wilder was exposed in the second fight. The man cannot fight off the back foot, and if you pressure him so much he can't line up for that perfect shot. In fact, you'll see his arms flapping around a lot in that fight, like he doesn't know how to deal with it. Hes used to getting outboxed, his opponent tiring, and then hoping that there's a gap for that perfect knockout.
Fury is the best, and has been for a long time in my book. He doesn't always look good though, but it really depends on who you put in front of him. I've seen him unmotivated to fight, and actually take a bit of a battering, and then I've seen the flipside where hes against a big name, and largely takes them apart. Even in the first fight against Wilder, I had him winning convincingly. He lost the round where he was knocked out of course, but what was brilliant was he got back up, and dominated the rest of the round from a nasty looking knockdown. Wilder was shook from there onwards.
