The FACT is that Ibeabuchi had half a career due to his mental illness which may or may not have been exacerbated by CTE (just throwing that out there). How he would have faired vs more well established/well rounded fighters is a mystery and how long his career would have lasted is also a mystery. Joe Mesi looked good to fight 10-20 more times right before he fought Jirov, ditto Magomed Abdusalamov. What I try to do is base how Ike Ibeabuchi was vs how other fighters from Nigeria did as pros. Yes there's plenty of room for error as David Izon is not Sam Peter and neither is Duncan Dokiwari, but there is a pattern fighters from Nigeria seem to follow. They start off looking like unstoppable beasts, they slow down, and they end up taking too much punishment from being in one too many battles.
