How is it? Stiverne got floored by feather-fisted Rossey in the first round, while Wilder couldn't even drop him over 12 rounds. It took him 9 rounds to KO Molina, while Arreola knocked him out in 1 round.
Decent puncher but not the huge puncher he was made out to be when he was KOing journeymen. The Liakhovich KO is by far his most impressive KO. Liakhovich is shot but he did go 10 rounds recently with Ruiz Jr and nobody had taken Liakhovich out like that before. But his inability to stop a less than 100% Stiverne or quickly KO Molina suggests his power is nothing remarkable.
^ very accurate BB. Good power but not great. Certainly not as good as a quick glance of his KO percentage indicates.
