Hardest puncher in the division, vs the most easy to hit fighter in the division, there's really only one outcome and that's Wilder by KO in rd 1.
One thing about Wilder, he's not a very good boxer, but he's a great athlete and one thing that Mark Breland taught him how to do that he actually does is blind people with the left (by either flicking it out or by using the left to pull down the guard) before dropping the right. This combined with the fact that Kownacki didn't even really try to defend.................yeah..........Kownacki isn't an educated enough boxer to beat Wilder
Kowanacki did have durability and workrate going for him along with a bit of power, but overall hes just not very good. Wilder KOs him fast.
Giant baby had a decent punch out put and a dig but that was about it. Wilder tools him. You can't have 0 defense against Wilder and get away with it. Wilder has lost every minute of every round against solid fighters not named Fury and still won by KO. Wilder wins by KO - Giant baby was never a top draw fighter.
