How Come Rhydon is rated 9.5 on this site

The ratings as well as move grades have been updated on GamePress, for your information. While I agree that Machamp gets 10, Dragonite and Tyranitar both get 9.5, how come Rhydon gets 9.5 as well?

As a defender, Rhydon has zero value. Most Rhydon defenders can't survive a Solar Beam from Eggy and die before using charge attack.
As an attacker, it's also underwhelming. MS/Earthquake is his current best and, the only use of it is to kill electric types (and since the combo has low DPS, he barely does the job better than generalist Dragonite). But we don't see many Electric in gyms. And clearly it fails to SOLO a Flareon/Jolteon boss, while other elite specialists can succeed with their speciality. Therefore, unless Magneton is common in the gym, I would never waste a single dust on any Rhydon.
Furthermore, GamePress demonstrates its weird love for Rhydon in even more places. You can see Rhydon listed as "Supreme Counters" to many Raid bosses. But almost no one wants those bosses. And don't forget the previous Attacker/Defender Tier lists where Rhydon was the center of debate.

Although I shouldn't care too much about the Pokémon ratings, I feel Iike the need to point this out. It's ridiculous. And FYI2, Golem, the Rock specialist which is greatly useful against legendary birds, rates only at 9.
