How many rounds did Floyd Mayweather Jr. lose in the last 3½ years of his career?

The now purportedly retired man who styled himself "TBE" ended with a run of seven consecutive decision victories: Miguel Cotto in 2012, Robert Guerrero and Saul Alvarez in 2013, Marcos Rene Maidana x2 in 2014, and Manny Pacquiao & Andre Berto in 2015. On the official judges' cards he averaged 8.6 rounds won to 3.4 rounds lost, winning 181 rounds total aggregated over the panel of three judges' cards over the seven contests, and losing 71. In other words, he won just shy of ¾ of the rounds in this span. He averaged 60-24 per individual scorecard over the entire seven.

(Full array: Cotto 10-2, 9-3, 9-3; Guerrero 9-3, 9-3, 9-3; Alvarez 8-4, 6-6, 9-3; Maidana I 8-4, 9-3, 6-6; Maidana II 8-4, 8-4, 7-5; Pacquiao 8-4, 10-2, 8-4; Berto 12-0, 9-3, 10-2)

I scored his fights 8-4 over Cotto, 11-1 over Guerrero, 12-0 over Alvarez, 8-4 over Maidana, 10-2 over Maidana in the rematch, 8-4 over Pacquiao, and 12-0 over Berto - averaging 9.8 won to 2.2 lost, 69-15. 82%.

Berto 83 of 495, 16%


That averages out to Mayweather landing 44% and his opponents collectively 21%.

1382 connected punches for Mayweather, averaging 197 per night, of 3,265 thrown, averaging 466 a night. Opponents landed 848 of 3,967 overall, averaging 121 of 567 per night

 

2 + 2 + 1 + 3 + 4 + 3 = exactly 15. :good

 

You had Cotto a shutout? :blood

 

Typo, 60-24.

 

Curious that some felt Mayweather vs. Canelo was among the closer ones.

Breaking down the ratio of punches landed and discrepancy in statistical accuracy between Mayweather and each of his seven opponents, we get this:

Mayweather landed 1.7 shots for every one landed by Cotto, with an overall 123% statistical edge in percentage connected.

1.7:1 over Guerrero with a 215% edge.

1.9:1 with Alvarez with a 209% edge.

~1:1 with Maidana with a 207% edge (Maidana landed roughly the same # but threw nearly twice as many).

1.3:1 in Maidana II with a 231% edge.

1.8:1 with Pacquiao with a 179% edge.

2.8:1 with Berto with a 350% edge.

The only person to do worse by either metric (ratio of Mayweather's connects versus their own and gap in accuracy percentage) is Berto, whom both the stats and the judges' cards bear out as having fared the worst by far against Mayweather.


Cotto, Maidana both times, and Pacquiao did better than Alvarez both on paper and on my cards. I awarded Guerrero one more round than Alvarez, who looked very ineffective that night, fought the wrong game plan, and by any measurement IMO did the 6th best (or rather second worst) job of the seven.

 

You don't have to bother. You missed 36min of nothing. :yep

I had it a shutout. There was a single round that many gave to Berto (the seventh, I think?) where it was a combination of a) Berto doing relatively better than he did in the entire first half, dropping from 90% getting-his-ass-whooped to about 70%, and b) the fact that he landed one single flush left hook on the chin that seemed to put Mayweather on notice and mildly scramble his circuits for about 2 seconds.

So if anything, seek out the 7th on YouTube and decide from there whether or not Berto deserved the round. That makes it either a clean sweep or 11-1. The rest were dominant and uneventful, trust me. :dead
