Some boxing enthusiasts said that Ugas instead should pick Keith Thurman first before jumping to Spence Jr. The reason is, Ugas has a chance to make another big paycheck before fighting Spence as the majority thinks that he can deal with Thurman as he was able to defeat Manny Pacquiao.
I think it's more of Ugas really wanted to have a big fight, so instead of waiting for Thurman, (which I personally was caught by surprise by his announcement that he will fight again). So it's the best option for now. And if Ugas will win against Spence, then he can either choose between Thurman or Spence.
Of course, that's just speculation, and what if Thurman won? No big fight opportunity will happen to Ugas now. It's a good decision for me that he go directly with the big one as Ugas is also hitting his veteran period now.
So it's prime vs prime fight here, and let's see which version are going to win. I will put Spence at a slight favorite here, but who knows, Ugas might pull a big surprised.
