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.
The OP basically ended the thread with his very own first post. Those are the top 3 fights to be made and imo also the top 3 fights out there in Boxing. Here’s hoping
