H2H GOATs don't get demolished in 2 rounds by Corrie Sanders. And Steward trained Wladimir was floored 3 times by Samuel Peter. You can't have a glass jaw and be cautious to exchange punches and be considered a H2H GOAT.
Lennox is still on top imo in terms of H2H. Because of his size, skill, and power. But Larry and Ali are both tied for number 2. Larry was more complete than Ali, but Ali was more athletically gifted
You know, there is why I can't see neither Wlad nor Lewis as H2H GOAT. H2H GOAT wouldn't get blitzed like Wlad was against Sanders or KTFOed with a single punch like Lewis was against Rahman. Add here Brewster fight fir Wlad and McCall fight for Lewis. Yes, they were great and could give any HW in history a hard fight. But they could also get KTFOed by somebody like Foreman or Liston for sure
