Yeah, his age really show in this fight, he is already in his 40's and with the effect of covid-19, it seems it will take some time for him to bounce back and recover.
There was a lot of speculation that Povetkin will have a good showing here, but Whyte really come prepared as he is more focus and really very careful not to get hit this time. It was a calculated risk, and then he caught Povetkin and it's over just like that.
It's the end of the road for Povetkin while, while Whyte's journey continues, there is no call for a third match it's obvious Whyte dominated the first two fights, this second fight is just a continuation of the first fight where Whyte dominate, only that deadly hook ruins everything for Whyte, his option now is open.
Probably there's one more fight left in Povetkin, but if ever he decided to quit boxing for good, then that's his decision. I agree that there should be no trilogy, it was not even close and we really know that Whyte will dominate again if ever there is a third fight.
There are a lot of option for Whyte, maybe Ortiz, Ruiz Jr, Hunter, Parker or Usyk.
