Would Tommy Hearns go through Sugar Ray Robinsons resume undefeated?

[Capaedia]

No way he would be undefeated.
Let's see who would he have to fight.
Jake LaMotta
Henry Armstrong
Kid Galivan
Randy Turpin
Rocky Graziano
Gene Fullmer
Carmen Basilio
just some of the greats he fought and with as many matches between LaMotta alone he would have at least 1 loss.

Armstrong was far past his best at that stage.

Out of those guys, I think Hearns would lose to LaMotta. It's unlikely he'd stop LaMotta, and Hearns had stamina issues sometimes, not something you want to have against LaMotta at all.

Outboxes Galivan, Turpin and Fullmer. Knocks out Basilio, Graziano and maybe Armstrong
