I'm not underestimating Thurman, but it seems he'll be having a hard time winning this one however you look at the match. With his significant height and reach advantage, even Fundora's jabs alone are probably enough to outpoint Thurman and defeat him via UD.
And given Thurman's age and probably ring rust, which definitely affects his reflex and agility, it's certainly a big challenge for him to be able to get inside and hurt Fundora from within.
If Thurman comes into this fight in good condition, I think he can win because he’s a smart boxer. Fundora may have beaten Tszyu, but in that fight Tszyu didn’t really make the right adjustments, which shows he doesn’t have the same ring IQ. Thurman on the other hand only lost to Pacquiao, and that was a pretty controversial one in my opinion.
I don’t care if he’s older, age is just a number, and Pacquiao already proved that in his fight against Barrios, and even though it ended in a draw, it was still a great fight.
I would have to agree with Darker45 here, the height and reach advantage of Fundora is going to be a big problem by Thurman. He really need to get closer to be able to hit Fundora with his power punches. But we have seen the Fundora has improved a lot against his lost to Brian Mendoza and has been using his jab more often now to keep distance and he uses this against Tim. And I would say that he also has power too. Although Thurman won his comeback fight, but maybe only a few of us here might be impressed with that because his opponent is not that well known.
