I'm not a fan of Tank at all but I'm in here anyways.
For the record, he was strong, his wrestling sucked, his punching power was undeniable, his cardio varied wildly but was generally trash, he was slow, his chin was decent but unremarkable, and his submission grappling was weak. He threw punches like a grizzly throws his paws around. He beat no one of any consequence and his biggest claims to fame and legitimacy is giving Oleg a long fight and Don Frye a tough 45 seconds. He gave us some great-looking KO's against limited fighters but always came up well short when put in there with good fighters, never mind great.
He was fun but in no way, shape, or form did he have it all. Not even close.
