If Joe Louis had never been born, the ballence of power in the heavyweight division might just have come down to this fight. Does Conn become a two division champion, or do the Baer family get the title back?
If Louis is never born, Schmelling by rights should win the title back, the title ends up in Germany (unless Schmelling defects). Schmelling is paraded world title, conquering everything in his path, like the arc from Raiders of the Lost Arc, the power of the World Title is so strong that Germany win WW2, the whole world speaks German and all the Jews and non Aryans of the world are killed in a mass holocaust Is that what you want Janitor, you Neo-Nazi
I think Buddy´s size combined with his good jab, fundamentals and power could be a big problem for Conn, ultimatly Conn would outspeed and outbox him for large parts of the fight. I don´t seem him getting dominated by Buddy´s jab - now put Wlad in there and this might be different - of course Baer might end it with a good punch. at some point. Conn clear UD.
Following this, the Draka would invade Europe from North Africa and put everyone under the Yoke. Pankration would replace boxing until an unknown youngster named Cassius Clay knocks out the Draka champion and ushers in a new era of peace and democracy. The peace would last until a small group of Afrikaaners steal a time machine and drug Jack Johnson during the Jeffries fight. The temporal waves from Johnson's defeat would travel backward in time, causing the South to win the Civil War. By 2011, however, very little will have changed from our time line, except that Jerry Quarry's cyborg head has become dictator of Earth.
Buddy was an extremely dangerous body puncher, and I believe that's what gets Billy out of there in the end. Conn had a fine record against heavyweights, but didn't take on first rate giants like Abe Simon and Buddy. Billy would need to get the big man into deep water, and hope to rally from behind to sneak the decision, but I suspect Buddy's body punching would take too much steam out of Conn for him to succeed late.
