- Errol Spence dominating his opponent when he return to the ring after a near-death car crash
- Keith Thurman dominating his opponent after 2 years rest
I don't like to put Science here but Spence experienced a worst but still a dominant fighter after he almost seen the door of the heaven on that car crash. Don't get me wrong and take that as a humor.
That might be some point of their life events but I do not think it has something do about their performance. Errol Spence has been dominating his opponent even before the accident, and Thurman, except Manny Pacquiao, had been dominating his opponent too. I think the good point of comparison between the two boxers is their performance fight against Shawn Porter and Danny Garcia. These two boxers were among their latest 5 opponents and they both beat them.
Watching the highlights of those fights[1][2][3][4], I believe the fight might go either way. Thurman fought the younger version of the two boxers and got an impressive result, and later Spence fought the two and also got a more dominating performance. Still, I believe the fight will be a matter of strategy like the one who counters the others. Spence maybe the favorite today because he has the belt but never estimate Thurman because he has shown that he still has that sting before he lost to Manny Pacquiao.

Yes, Thurman fought the younger versions of Porter and Garcia. Garcia was also undefeated and a champion at that time, so it was a unification and a battle of undefeated champions.
But after Thurman went inactive for 2 years, he changed and seems lost. I don't see the hunger in Thurman anymore. In his return fight against Lopez, he won but there were times when he struggled and then all of a sudden he jumped right away to fight against Pacman although an older version. After earning millions he went inactive for 2 years again. He made another tune-up against Barrios, a 140 fighter who was knockout in his last fight against a blown-up 135 Tank Davis. It was a clear victory for Thurman but he struggled and was so vulnerable and was the one hunted by Barrios. Imagine if it was Spence in front of Thurman. If Thurman cannot stop Barrios, how can he get the respect of Spence? If Thurman was hittable and was shaken that's why he ran away from Barrios, imagine if it is a real welterweight with the power, toughness, and skill of Spence.
I can only speculate what had happen to Thurman during that time,
a. It really took a lot of toll in his body, the wear and tear and so he had to recover from those injuries
b. Choosing a wrong fighter in his comeback, not sure why they chooses Josesito Lopez, but that dude is what tough SOB. Others could look at how durable this fighter is, fights like against Victor Ortiz. He even had fight with Canelo Alvarez
c. They rushed him in making a comeback and maybe he is not 100% yet when he fought Lopez
And that's why Pacquiao and coach Roach is willing to fight him because they see something in him in the Lopez fight. That he wasn't the same anymore.
But again, let's see, if a big fan ahead of him, and maybe at least he can motivate himself again to make this a war against Spence.
