I am all for bad and shady characters in tennis provided they ultimately provide the goods. Perfect case in this would be someone like Agassi. Was an anti-establishment, a tennis rebel, prodigous talented etc. but ultimately he did a lot for the sport by foremostly making use of his talent and winning grand slams. And now he is a perfect Ambassador for Tennis supporting NGO projects and so on.
Thats the reason why Rios doesnt even come in the scheme of things. He had talent so what ? Can name a hundred other players who were as talented and their GS career was as uneventful.
Medvedev,Rosset,Stich,Krajicek,Safin(To some extend),Hicham Arazi,Alami,Nalbandian and so on. Just because he meant a lot to Chile and to some extend South Americans doesnt means he means a lot to the rest of them.
Had hardly noticed Rios's career primarily because Agassi 2.0 was still in the making and Sampras had an offish sort of year and it was a weak era and Rios was there at the right time and its not as if he was there for a long time. Just when the limelight was on him the light went off him too. Really nothing special
But having said that whatever floats your boat or whatever makes Amigos and Esparantos happy. If Rios rocks your boat then why we want disturb the decorum.
