The 90's Bulls teams were head and shoulders above their competition at the highest level and when it counted most, in the playoffs, which is why they only went to one Game 7. GS may have set a record during the regular season this year, but they are far from outclassing their playoff peers like the Bulls did.
Warriors fans also concede they aren't that great by claiming there is more parity in the league. While it may be an obfuscated attempt to promote the strength of other teams so the warriors' iniquities can be dismissed, they are simply admitting their team much closer to a middle-of-the-pack team than the 90's Bulls were.
