Lessner got hand fed that opponent - Kim is winless in MMA - Kim has zero stand up - I'd like to see Lessner fight a real HWY that has some take down defense - but he certainly is massive and has high level wrestling.
I think he's 2-5 in MMA for what it's worth. Either way, he's never going to be a contender. He's good enough in judo tournaments but that's about it.
