1. Jose was offered a rematch. He turned it down. I don't care if it's 11 days notice. He was bitching about it nonstop afterwards, and he claimed he was staying in shape in case RDA pulled out. He could of gotten his revenge, like he said he wanted, regardless if it was for the 145 title.
2. I don't think many people would call it an upset right now, Conor's went on to become a two-weight champion, I think it's safe to say he'd be favored in a rematch.
3. Conor is a few inches taller than a lot of the guys he fought (Though shorter than Max) but you make it sound like he towers over them.
4. Comparing McGregor to Serra? I can only assume you are trolling like I was when said he was the GOAT, because that's ridiculous.
If he didn't fight again, Conor will be remembered as a two-division champion, a fighter who with a deadly left hand and top notch counters. Hardly what you said he would be remembered as, huh? Maybe not GOAT levels like I joked (and will continue to say in response to terms like McNuggets) but that's reserved for the likes of Fedor, Silva, and GSP.
1. Aldo was under medical suspension, he couldn't take the fight even if he wanted to, and even if he wasn't, he deserved much better than to have to fill in on short notice for one of Conor's opponents. The UFC treated every dominant champion before him better than they treated Aldo.
2. It was an upset. Aldo is the unquestionable FW GOAT, and no one else comes close. Even the people who thought McGregor would win were shocked how it happened. There is a reason the phrase "flash KO" exist. The whole story wasn't told in that fight, and rather than stay and defend his belt McGregor was allowed by the UFC to move up.
3. McGregor has had a sizeable reach or height advantage, if not both, over pretty much every one he's ever fought. That will define more of his career than Aldo losing in what will probably go down in history as a freak KO.
4. Comparing McGregor to Serra is perfectly acceptable as neither ever defended their title. Actually, at least Serra tried.
As it stands McGregor being a 2 division champ will forever be marred by the fact the UFC made it easy on him and facilitated the accomplishment in no small part. History will chronicle how McGregor was alllowed to shirk his duties as champion, how he never defended his FW belt, how he held up the FW division going 1-1 with a LW gatekeeper at WW, was then gifted a LW title shot against a weak champion (also smaller than McGregor), was then was stripped of the FW belt, and then held up the LW division only to be stripped of that belt as well.
The feat of multiple simultaneous championships will be replicated eventually by fighters who didn't have opportunities handed to them when they were unworthy. People will remember that.
If McGregor goes down as the worst UFC champion in history, he deserves it.
