I think Tito takes it.
Huge fan of Shogun, but he didn't look good in his last fight. Like, before, he looked slower and less Shogun-y, but he still had that incredible KO power in his hands. Against Lil Nog the second time, he landed clean, but didn't even bother Nog. I think he should retire after Rashad, hopefully with a final KO win, unless his power truly has left him.
