Yeah I get that, even though he's still a 'fresh' 46 year old and probably needs some cash as well as he's fighting these top opponents. His punch resistance is clearly affected though. If he loses against the guys I've mentioned (add Stiverne, Molina, Scott, Adamek to that list), he definitely should retire.
He definitely deserves a bigger fight in 2019. He beat Chisora (pretty comfortably), Rudenko (only guy who knocked him down ever), Hubeaux (as clean as or even better than Rivas) and Rovcanin (had a draw with Dimitrenko who just fought Jennings). I think Jennings would be a good matchup for him to step up. Maybe also Povetkin in Germany.
Sergey Kuzmin: Thanks to everyone who was sick and worried. Today we won again, but we had to suffer: in the second round I was injured (a crack with a fracture of the left thumb). But do not give the same victory. I'll heal the injury and in summer I'll be back in the ring
On Efe, he's very tall, a little stiff, but his accuracy and power impressed me. Reach was 85". The 88" was hard to believe in the first place. The right hand and the uppercut, you don't want to get hit by it. Mansour was game, but too small and overmatched. Ajagba didn't fall for the counter trap. All I need to do is see Ajagba go 8 - 10 rounds and take a medium level punch without distress and I'm picking him vs. some in the top ten already. I do wonder how old Efe Ajagba is. He had quite of bit of grey in his beard.
Not good performance by Kuzmin. But I wouldn't write him off straight away. In this fight Kuzmin was waiting for Davejko to go at him but it never happened, Davejko is too smart for that. You can see that Kuzmin had trouble figuring out Davejko's style. Altough it was dissapointing performance by Kuzmin, he is ranked pretty high, so he will get bigger fights in the future and those fights will show his true ceiling.
Mansour got hit with a PED infraction after his fight with Kuzmin was halted. When a 45+ year-old fighter comes down off his PEDs - he usually comes down hard. I do think Mansour should retire very soon. But I could also see him as a step-up guy for Darmani Rock. Roc Nation made some noise about wanting to step up Rock for his next fight and Mansour is from Wilmington, Delaware - which is close to Philadelphia. Rock should outclass him but he's not likely to bomb him out of there. As a step-up fighter Mansour would be a good fit and he'd probably get the chance to take a last fight with decent money, some friendly faces in the stands, and no real chance of winding up in a hospital.
I really don't see any fighters in the USA wanting work with Ajagba right now. Maybe a guy like Bryant Jennings who is about to have his career slip away and needs to make huge waves is a possibility....but I wouldn't even bet on that. Efe is a bit stiff. I'd like to see how he fares with fighters like Hughie Fury or maybe Fedosov.
