Why people are so biased towards Ali era

I meat dont get me wrong but beat Ali=that makes your elite fighter other guys struggles against someone=look this guy struggled with some bum but when Ali struggles against someone=Omg ATG Leon Spinks was journeyman yet you Ali fans hype him like he was different than mcbride what makes Spinks great fighter and Mcbride journeyman. Lyle, Young Folley, Norton are sure not different than Ruddock, Bruno, Grant, if were being honest. 60s 70s heavyweights are not technically much different than today's scrubs in reality. What makes that fighters different because they put great fight vs Ali and get praised and mytholized as a ATGS someone put good fight against today's scrubs or vs Mike Tyson =that opponent sucks nothing special 0 credit That guys werent that skilled all were mostly some sluggers compare to 80s 90s HWS in terms of skills 70s HWS are not even close. C level fighters like Chuvalo are mytholized as a great because they fough in that golden era but todays champions or in Holmes era are bums. Norton my boy don't deserved even to be names as a great fighter let Alone to be in Hall Of Fame but again he make his name by beating Ali. In fact most of these guys are nothing special at all compared to some other solid contenders and heavyweight champions they are hyped because they put tough fight vs Ali someone like cooper was seen as a great fighter Spinks too Ali simple wasn't that great these guys just are so overrated Take Ali out of the picture and the guys career is nothing special.In fact Ali was special that he actually uplifts other people to mythic proportions. Joe Frazier: don't get me wrong but he is very overrated for me That trilogy is his one and only claim to fame.Without it,nobody would remember him in the slightest. He lost this trilogy decisively.And despite losing this trilogy,Frazier is usually remembered above far greater fighters than himself.Without that trilogy,he wouldn't even make it into the hall of fame. Legitimate greats like Michael Spinks are all but forgotten except for some highlight package of young phemom at his peak.who dominated everyone in LHW division.
