Lewis's resume was waaay better than Klitschko. Holyfield, Mike Tyson, David Tua, Vitali, Ray Mercer, Tommy Morrison, Michael Grant (when he was undefeated), Shannon Briggs, Golota, etc. It's a better resume than both Klitschko's combined tbh.
I don't even know who Wlads best win is, Chris Byrd? Sam Peter? David Haye? Think that's about it as far as solid wins. Of course it's not his fault the division sucks, just sayin.
