Depends which Sanders shows up. If Sanders comes to KO Hrgovic he might blow his wad and get stiffed himself. If Sanders came to box, then I think he could outpoint Filip by a wide margin. People forget that before Corrie started switching people off, he was primarily a fast mobile boxer with a jab.
Sanders was freaking fast for someone that size and could really box when he wanted to. And he could throw punches in impressive combinations.
Sanders often came in hot, but was almost always sucking wind by mid rounds. Hrgovic outlasts him and stops him late after being down on the cards. No different than Sanders vs Vitali.
I didn't say Sanders had no chance. But, the Puritty fight was more the exception than the rule. Sanders rarely came in top shape to go 12. Even against Wlad he was in sub-par shape. Luckily for him, Wlad's chin couldn't last until deeper waters. And, against Vitali, he had the chance to turn his entire career around, but, showed up again in sub-optimal shape.
Corrie could box real well when he wanted to and was in shape. As long as he doesn’t gas I think he takes a decision
Which is why I said it depends on which version of Sanders we are talking about. The versions of Sanders you are picking are from when he was old. Frankly I think his younger, boxing oriented version would box the ears off Hrgovic. If he came to blast Hrgovic away it could go pear shaped because Hrgovic is as tough as they come.
