Louis. No light-heavyweight can outmuscle Louis and if Kovalev tries to box he gets broken down, sooner rather than later. He's no Billy Conn.
Louis by ko in 3-4 rounds but I'll take the bait. Kovalev would be well in the 190s or higher if he didn't cut weight and he has enough punching power to hurt a 200-210 lb heavy who was dropped multiple times by Joe Walcott, so it's not a bad matchup, physically. Problem is that Kovalev doesn't have the foot speed to exploit Louis' leaden feet, has slower hands, a much shorter reach, and no experience with his kind of power.
Or did he give me an opportunity to reiterate the truth? I'm picking Louis here. But I think Kovalev much like the best boxers Louis fought that were smaller than he could win plenty of rounds, and perhaps even floor Louis, who was knockdown prone and would be facing a man who hit far harder than the 168 pound Conn who stunned Louis. It would be interesting to see how Louis takes Kovalev's punch because he's an accurate puncher with top level power for a light heavyweight. Kovalev fights in the 180's on fight night, so he's not giving up that much weight vs a 197-205 pound Louis. In addition, in some fights the score cards for Louis looked rather off in his favor. Essentially Kovalev needs to either get a KO, or author a complete pasting like Charles did if the fight took place in Louis' era. Kovalev is not likely to win a decision with Louis management picking the ref's if the fight was close. So I'll go with Louis via TKO, but I'd also say Kovalev can make a good showing and expose Louis' flaws in terms of footwork. adapting on the fly, and defense. Now all that's left is for McVey to ask which cards were suspect, and I can list a few. So McGrain, how did I do?
You might be right about that. Charles and Schmeling were decent boxers too. Charles easily outpointed Louis and Schmeling who did the same knocked him out. For sure Kovalev hits harder than Charles. We can argue who hit harder between Krusher and Schmeling, especially if Krusher had those lighter gloves Hopkins, known for defense and countering was completely outboxed by Kovalev. Louis did not have a defense near Hopkins. But Joe could punch a ton, and Kovalev's chin is untested vs top end power.
This thread is better than that Joe Louis vs Joe Calzaghe thing that was posted here a while ago. That's all I can say for it.
