In no order, off the top of my head: Dominique Wilkins, Chauncey Billups, Chris Webber, Reggie Miller, Kobe Bryant, Jason Kidd, Chris Paul, Oscar Robertson IMO..
I don't think Oscar was that overrated, tbh. He did have inflated stats and all and only rang once as a 2nd banana to Kareem (though he did play well) but he had mad game. As far as overrating him goes I don't see anyone putting him near top 10 these days, but he was a legend during his era.
