Speaking of Spence, I have just watched is fight with Ugas. Ugas is a very good welterweight, one of the better ones out there, Spence wins by TKO on the doctors stoppage.
This is probably the first time I can recall Spence getting hurt, he was badly hurt by Ugas in round 6 I think. At 32 and with lots of problems out the ring and lots of injuries I don't think Spence has really pushed on at all from when he dismantled Brook in 2017. He's still a top welter, but he's shipping more punishment and Ugas, a fairly light puncher, was hurting him.
He still has a lot going for him, a multi-faceted attack which incorporates a lot of body work and subtle level changes, good power and in fighting etc. A fight with Crawford is next logic step for the division in general as it would unify all four belts and would be an intriguing fight and clash of styles.
