These are my 3. #1. Fury vs Usyk - Heavyweights stand alone, above all others. This would be two undefeated heavyweight champions going for undisputed. #2. Spence vs Crawford - Two undefeated Welterweights and top p4p fighters fighter for the undisputed Welterweight crown. #3. Beterbiev vs Bivol - Two undefeated Light Heavyweights for undisputed Light Heavyweight crown. All three of these realistically can be made by the end of this year, and definitely, by the end of 2023.
