I agree with you that a world medal is a feather in Micic's cap. He did what he needed to do to get on that stage and capitalized on his opportunity. That's awesome!
I just think that in the totality of somebody's career, if you want to be considered the GOAT then you have to do it at all levels. High School(minimum state champ), College(minimum National Champ), International(minimum sr world/olympic medal). Right now we have a bunch of guys that have accomplished 2 of the 3. Angel, Howe, Nick Lee, Parris, Micic. IMO those are your 5 candidates for the IN GOAT at this time. Of that group, only Lee and Parris have a chance to still get that 3rd milestone. Parris does have a Jr world title, so that would tip the scales in his favor if neither Lee nor Parris get that sr world/olympic medal
