Oscar is a good fighter but best at 154,no way. Not by rankings,not by opponents faced Karmazin,Spinks,Simms(would be a STYLISTIC NIGHTMARE for Oscar) Garcia,Ouma if he comes back down, etc These guys would allll give Oscar a tough fight,no way can anyone say Oscar is the best at 154 conclusively,not now. Prime Oscar then yeah,for sure. The Oscar that beat Vargas,yep but that was 5 years ago.
