Wilder would outbox Joshua at this point, possibly even KO him! He just went life and death with Whyte.
In my opinion Wilder would be out of his depth and get stopped early. I don't believe Wilder has any more power than Whyte threw at Joshua tonight and he couldn't stop him so how would Wilder? Couple this with Wilder's chicken legs and I see Wilder being much more likely to be stopped earlier than how far the fight went tonight.
Form what I saw today, this would be a great matchup for Wilder. Fast combos is what Joshua looked very succeptible to, and his endurance is still questionable. Wilder has the stamina, movement and power to really make him pay. On the other hand though, how does he deal with Joshua's power. This is why this is such a fascinating matchup down the line.
Who has the better chin is still a question mark but Joshua is the better boxer, I have no doubt about that now.
I have a feeling haye would win he would evade joshua jab and cross and get inside and could KO joshua
