Hes an Usyk CW opponent whose only loss at HW was a split decision to Wallin. If you're wondering why fellow Usyk CW opponent Hunter is ranked 12th with no losses and the Bakole win it might be because Gassiev is 5 years younger. But Rings rankings don't make sense. Sanchez is 22nd, Jared Anderson is 19th and Hrgovic is 16th based on competitve losses to top 5 fighters. Pulev is 17th based on winning the prestigious WBA(Please don't sue us) belt. Andy Ruiz is ranked 21st when hes 1-1-1 since beating AJ 6 years ago. The Ring top 25 is mostly the real 25 the order might as well be random.
For some reason on BoxRec if you beat someone ranked 10th in the CW division or any other division and then move up - you basically keep that ranking. Makes no sense that he is 8th. Gassiev literally lost to Wallin.
