Nigerian middleweight prospect Israel Adesanya (12-0) dazzles in his UFC debut at UFC 221 in Perth, Australia. The MMA world was buzzing about Adesanya's Octagon debut and he did not disappoint, knocking out Rob Wilkinson in the second round. That's 12 knockouts in 12 professional MMA fights for Adesanya, who trains out of New Zealand and is an accomplished kickboxer. Oozes confidence. Very fun addition to 185-pound division.
