a quote from michael from the story 'Marvin, here I am. If you want a big payday, come on and get me. Marvin is awesome and so am I. I want to see Marvin come right up and meet the Spinks Jinx.'

this was after the oscar rivadeneyra fight, i find it extremely hard to believe michael called out marvin & the boxing community didn't talk about that fight
