Not trying to be a dick
@Cooliox, but, were you around then? I remember prime Chuck (Awaiting for Tito to come back fro injury so the could have their title shot) sweating to decision true MW Bustamante (A BJJ guy with not wrestling, the easys stylistc matchup possible), decisioning fat WW Suloev (A "full contact" kiboxer with no knowlegde about checking low kicks and nebulous grappling credentials) with very little dominance, being beaten by fist ,and then struggle to (Before the eyepoke) Randy, being thrashed twice by Rampage, decisioning Vitor...
Even when he Knocked out in impressive fashion , Mezger, the Reem (Both were fighting better before the knockout), Babalu... even shot journeyman Vernon (Eyepoke or not eyepoke); neither of them were scared of him. Only Tito was.
Not to mention tha no one that wasn't an UFC full retard nuthugger considered him the nr. 1 LHW of that time, in any period. In fact most people didn't consider him top 3 LHW at his tittle reign, placing him behind Wandy, Arona, Rampage and Shogun.
Chuck was very good and exciting, but comparing him to Tyson is either ingnorant of just plain stupid.
