I don't know bro Jacobs was a big dude. I think besides Canelo, Pirog, Golovkin, and Rosado, Jacobs simply beats every middleweight in history
Jacobs unanimous decision Boxing has evolved drastically. Those guys have no chance. Jacobs is bigger, smarter, and more skilled than those guys and his resume is excellent. Sergio Mora, Sergiy Derevyanchenko, Peter Quillin, Caleb Traux. The second best MW resume I've ever seen in my life Nunn is nowhere near as skilled as Jacobs. He gets schooled
His first round v Hagler is better than anything Jacobs ever did and he stopped Roldan who was tougher and better than anybody Jacobs has stopped, he also stopped Shuler with one shot in the first round, Jacobs has no KO that can match that.
Jacobs walks down Hearns and shatters his glass jaw like he did Quillin except Hearns' eyes roll to the back of his head
Jacobs would have very little chance to beat Nunn. He's not beaten a top of the line fighter so assuming this is prime against prime this is an easy Nunn victory.
