I think Mike was too big for Duran at 154 and would've won that fight, but I think Leonard was just a little too fast and too good for him. Hagler and Hearns would've been great match ups for him, but both would've had to rely on speed to beat him. Maybe prime Hagler could've won a 12 or 15 round war, but he would've been better served to box in that one and not stand for to toe. The Tommy fight is fascinating in that I think Tommy's reach and speed would've really bothered McCallum, but I think Mikes durability, chin, underrated boxing skills and body attack would've had him coming on strong late in the fight. Not sure if Tommy had the stamina and chin to survive the distance in that one.
