How would Joe Calzaghe do against today's champs?

At 175 it's hard to say because Joe only fought there a couple of times when he was getting old against guys who were ex middleweights. I could actually see Joe fighting smart and using his speed to win a decision against Beterbiev. Wouldn't be confident but I could see it happening. Not sure how he would do against Bivol either but if I had to pick, I'd probably go with Bivol by decision.

High workrate fighters never have the same kind of volume vs counterpunchers but I do think he might beat Canelo. I agree his workrate would drop but it would still be enough imo combined with Canelo's lack of height and slow feet. Calzaghe was a similar size to Bivol really.

He beats Canelo, too much workrate. Calzaghe vs Benavidez would be a really fun fight. High workrate fighters never have the same kind of volume vs counterpunchers but I do think he might beat Canelo.

Beats everyone at SMW but Benavidez I just don't think he has the power too keep him off LHW - Beats everyone with ease apart from Bivol & Beterbiev. I think he drops a decision to Bivol & gets stopped late vs Beterbiev in a fight he maybe ahead in.

Can you an elite, in his prime fighter that Calzaghe fought?

Canelo vs Calzaghe would be interesting. Has controversial decision written all over it. Quality vs Quantity. Beterbiev stops him IMO. I’d favour Bivol by decision, but Joe was always very hard to beat on points due to his volume and work rate.

Calzaghe would beat Alvarez, and I don't think he would drop a single round 'Stylistically not a good match up for Alvarez'. Note: So I believe Calzaghe would do very well at 168 pounds 'And he would be a Champion' etc.

hes smack tank and shakur around the ring, slappy style
