Given who started this thread, it was pretty obvious that this was a poorly camouflaged Khabib worship thread. That said, as a Tony fan I will still try to offer some objective analysis.
Tony's best win is **probably** RDA. The eye poke stuff is nonsense. Tony has ZERO history of doing it, none. So while it did happen, it was obviously accidental. In addition, RDA actually edged rd 3 on the judges cards (eye poke happened in rd 2). So it can't have affected him that badly can it? Tony won because he turned up the pressure and threw ridiculous volume at RDA in rds 4 and 5 in Mexico City where EVERYONE else noticeably tired as their fights went on.
Tibau is probably an underrated win given that Tibau was roided to the gills and coming off 3 wins in a row. And the ease in which Tony dominated him was surprising too.
And of course this thread did quickly turn into a comparison of Khabib and Tony's resumes so I guess I will throw my 2 cents in there. Unlike TS and most of the people here who worship Khabib I can be objective. So while I think Tony's losses are meaningless from the perspective of who he is now and his chances vs Khabib, I can also acknowledge that from a resume' standpoint they do matter (at least a little). And while Khabib may have been a little lucky to get the dec vs Tibau, he did still get it so remains unbeaten. And while it was a lot of can crushing in Russia (aside from maybe 3 guys) he did still run through them like he should have.
Conor being out 2 years and basically having had 1 LW fight doesn't make it a huge win when looked at closely, but the general enormity of the fight and (deserving or not) the fact that Conor was the LW champ does make it a meaningful win.
So while I do like Tony's chances to beat Khabib (for reasons I've explained a bunch of times), looking at it objectively I'd have to give Khabib the slight nod as of now when it comes to overall resume'.
