Michael's biggest wins were Larry Holmes and the two Muhammad's if you ask me. Cooney was tough, he was a big guy with a lot of power, but he was derailed big time by the Holmes defeat.
Very smart,technical fighter and underrated in my opinion to many folks. I'm surprised I didn't become a fan of his after the Qawi fight but I agree his awkwardness was his best asset.
Watching his win over Holmes is baffling. The seemingly superior boxer (past it or no) is just beaten to the punch and made to lunge by someone who seems like they should be getting hit more. I think the "speed vs. timing" dynamic can be applied to one's legs as well as one's punches. Spinks didn't really appear to be the quickest guy on his feet but moved at just the right moment.
It was great how if an opponent thought he had Spinks cornered, he could turn them, assert himself offensively and just start pounding away, all of a sudden the danger is trickling down a different path, headed for his opponent. At 175 he had great physical strength, really good, it's not usually the standout attribute with skilled boxers, but a lot of them posess it regardless, and Mike Spinks was one of them. He showed so much heart against Holmes, in that first fight, i remember first time i watched it. Even though i knew the outcome, in about round ten, Holmes started literally chopping away at his torso, and i'm sitting there feeling for Mike, like i say even though i knew the outcome. Thinking to myself, 'there's still 5 rounds to go', he looks like he might wilt, only to come back and land the better shots and win the fight. That's when i was convinced to my core that the absence of fifteen round fights today is a huge shame, and an element of the sport that would have found out a lot of fighters.
