What does Canelo have to do to be an all time great?

Transport himself to the 80s and beat real boxers.

 

No.

A man who stacks hand wraps, pays judges, takes PEDs, uses every weight manipulation trick in the book and stacks everything else you can think of in his favour, on top of cherry picking the worst champions in the division will never be an ATG.

 

He lost the 2nd fight against GGG too.

 

Beat great/very good fighters without needing gifts.

 

He probably needs some legitimate, uncontroversial wins over prime/young contenders who are comfortable at whatever weight the fight is made at.
That would be a good start.

 

Well,Canelo fought 1 proven ATG in Mayweather Jr. who's is a natural Jr.lightweight.
that had shown very little punching power at the weight they fought at. Canelo lost
almost every rd.
That's a bad start to proving greatness.

 

KO his next 10 opponents including GGG, Beterbiev, Bivol and Charlo brothers.

Ain't happening.

 

For a start he must beat prime top fighters (not washed up, not welters, not too old, not Rocky Fieldings). And beat them convicingly

 

Head-to-head, we're seeing the best of Canelo now, and frankly, I don't think it's good enough to warrant ATG status. He's a really good fighter in a relatively mediocre era at middleweight and super middleweight. GGG at this age is nothing historically special at all (it's arguable if he ever was), and Canelo barely got by him, needing a gift in the first fight. He was also clearly not ATG-level at 154 having squeaked by Lara, edging Trout, and getting utterly dominated by Mayweather.

Canelo's legacy will be that of a very good fighter who beat a bunch of good to really solid fighters, but never had a convincing win over a great one, let alone a true all-time great. If you heavily weigh depth and numerical accomplishments, he could be an ATG in that sense I suppose. I tend to think he's a bit manufactured though despite obviously being a damn good talent and a hell of a fighter.

 

Retire now. Otherwise he will be exposed. Should follow Andre Ward's lead.

 

Stop GGG in the rematch and somehow convince Ward to fight him and beat Ward, and take on Saunders and have some title defenses in some of the belts he wins.
