Mention the last 5 fights with Mayweather-Canelo type of anticipation?

Honestly I think you have to go back decades to find fights with this type of appeal. You have to factor in both the style differences and the age differences, add that both are unbeaten and throw in a dash of ethnic rivalry to get just the right type of fight that Mayweather/Alvarez bring to the table. I don't think you can find many match ups of an unbeaten boxer vs and unbeaten slugger of this nature and magnitude, it's that big, but I will try.

1.) The one that jumped out at me first was 68-0 Chavez Sr. vs 24-0-1 Meldrick Taylor I, and it lived up to all expectations. It went down in history as an all time classic with a story book ending. The age factor was lacking, but both were unbeaten at the time, you had the ethnic angle and the styles were similar. This one mirrors the Mayweather/Alvarez fight quite closely.

2.) Another is Salvador Sanchez vs Azuma Nelson, although not as pronounced a style difference, Sanchez played the roll of the slugger, Nelson a surprisingly game boxer, and it ended in the 15th round after another classic. Both were unbeaten at the time, and although it didn't pit an American vs a Mexican, Azuma did add that bit of ethnic flare that Mayweather vs Alvarez brings. Nobody expected the young Nelson to emerge as a star against the heavily favored Sanchez, but this one is still a classic.

3.) Julio Cesar Chavez vs Pernell Whitaker, the classic slugger vs boxer, I though it shouldn't have been a draw, I though Whitaker won, and it didn't have two unbeaten fighters facing each other, but the anticipation level for this one might have been greater than that of Mayweather vs Alvarez. This one lived up to the hype, and it's controversial ending still rings loudly decades later.

4. Ali/Frazier I put an unbeaten master boxer in against an unbeaten slugger, and the slugger won in convincing fashion with a late knock down to seal any doubts. This one lacks the ethnic aspect, but not the anticipation, in fact Ali/Frazier I was one of history most anticipated fights and is far bigger than any lesser weight fight. but because of it's historical magnitude it warrants mention.

5) 32-0 Thomas Hearns vs 30-1 Ray Leonard, while not a battle of unbeaten's and lacking the ethnic angle, did pit the era's most fearsome puncher against the era's best boxer. It far eclipsed the anticipation level of Mayweather/Alvarez, and it certainly lived up to the pre-fight build up. Classic mega fight.

I am sure there are other historical mega fights with similar comparisons, but these five were some of the biggest ones. Given the ridiculous amounts of money a Mayweather fight generates, the Floyd/Canelo fight might just set financial records, but it is unlikely to live up the the legacies of the historical mega fights of the past.

Mayweather-Cotto

Mayweather-Mosley

In both those bouts, Mosley and Cotto were given some chance of testing, threatening if not outright beating Floyd. Of course, they did in some stretches especially Cotto but Floyd managed to ride over the storm and win with plenty to spare.

Pacquiao-Marquez 4

In this fourth meeting of the two bitter ring rivals, many so-called experts said that Pacquiao had improved so greatly after their last meeting at 130 lbs. and with the fight set at 147 lbs., the Filipino would win decisively, some saying even by early round KO/TKO. But many fans and pundits alike who really knew their boxing stuck to their gut feel that it would be an evenly fought match that could go either way.

Martinez-Chavez

Rios Alvarado 1

Mayweather/ Cotto, which did the 2d applicable in non-Heavyweight PPV to Mayweather/ De l. a. Hoya. I anticipate Mayweather/ Alvarez to triumph over the Cotto numbers and challenge the De l. a. Hoya numbers.

Mayweather- De La Hoya

Pacquaio- Cotto

Roy Jones- Calzaghe

Lewis- Tyson

Jones- Ruiz

All of them were great fights.
