It's hard to imagine that Ugas will win here, if Spence is fully healthy, I think we are going to see a KO win from him as Ugas would only be a standing target since he cannot take advantage using his lenght like what he did on Pacquioa.
Well I think that many do not have very good expectations for Ugas, on the other hand with Spence I see that there are many beautiful hopes and they expect victory from him, of course waiting for him to achieve a KO would leave everyone with their mouths open, but I think that UGAS has considered this option and your preparation will be much tougher than before.
However, when reviewing some articles I see that they put Spence with more options to win over UGAS, the statistics in boxing are usually much more efficient than in any other sport, at least it is what I have seen due to my little experience.
