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.
