2 bouts: 10 rounds and a 15 round rematch.

Conn UD or Baer KO are the only 2 possibilities.

I'd lean toward Conn.

Either Conn outboxes Baer behind his jabs, movement and counterpunches without engaging him on the inside or should Conn tried to slug Baer like in his first Joe Louis fight, Baer would catch him in the late rounds and knocking him out with a big right hand.

Conn beats him by UD.
Much more skilled. Baer might rattle him a couple times but Conns fast combos and lateral movement would have Max swinging at air
