I'm going Tyson. sometimes Ali went into the RJJ "I'll just toy with my opponents" mode. Tyson genuinely looked like he wanted to kill people in the ring.
Since i'm not a fan of shoeshining till someone gets really tired and then deciding to put a little mustard on them, i'll go for Tyson. Although I'll say that Ali was pretty good at shoeshining. The grand master of slaps.
I have him as much ahead of Tyson as I have Holmes over Louis in that regard. :thumbsup I hope you do that thread too.
Seriously, this is close. The ones Tyson had hurt and couldn't finish off was Tillis and Ruddock (rematch). For Ali (as I can recall) it was Terrell and MacFoster, with Shavers being a borderline case. And they both finished off fighters that no one else finished.
