Errol is almost as soft as Devin Haney being exposed, all the time in their career they were just fighting low-level boxers playing numbers for their boxing records but when they are matched to someone just right where their skillset level, they fold in the ring.
Fundora is also the same but after fighting Tszyu, he proved himself. I think Fundora will battle Spence to the ground.
It was speculated that the reason why Errol Spence did not have a strong fight vs. Bud Crawford is because Errol is very much dehydrated in welterweight. He is becoming very heavy for this weight division already. Also, similar to what @bisdak40 has mentioned, Fundora is not a very good boxer. This fight for Errol is the tune up fight that he needs hehe. However, a tune up fight with a championship hehehehehe.
I'm not sure if he is dehydrated or not when he fought Crawford at 147 lbs, both could be rehydrated as well as Bud is also moving at 154 lbs in his next fight. And just shows that Crawford really dominated a prime Spence that time and there's no question who is the best Welterweight.
However, this is going to be a make or break fight for Spence, and I think his fans can't wait for this fight as well as Errol will proved to everyone that he still have it. Ring rust though might play a big role here. So respect for him for not taking a tune up.
