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.
A risk that is worth taking, I think this is what Spence is thinking in this fight. And for me, we can compare this to Tank fighting Mario Barrios for a belt at 140 lbs. So I will take a word from you, this could be a "scam" as Spence has a great chance to win this fight.
In paper it looks good for Fundora as he won against Tim Tszyu, however, if not for the accidental cut, it could be a different outcome and Tim could have won the fight. And another factor is that they know that Fundora just came from that messy fight and so he might not have recovered yet.
