So he is brilliant, no doubt about it! He wins when he isn't supposed to, plus he has found ways to win in his 40's and prolong his career at the highest level.
He has to go down as an all time great, and I'm not even his biggest fan.
Now by the time his fight with Kovalev comes around in November, he wont have had a KO for over a decade.
Also, he's had 16 fights since his last knockout against De La Hoya in September of 2004, with 15 of them going the 12 round distance (with one NC vs Chad Dawson that lasted about a round and a half.) and he doesn't seem particularly shot from the constant long fights.
So has he lost the power he did have? Is it simply because he has been fighting very good opposition for so long? Has he developed a style the requires him to preserve energy and just forget about trying for knockouts?
What do you think it is?
