Did he lose concentration against Tate and Kalambay? Be objective and stop cherrypicking, canelo stan.
LOLOL using the < 1rd Kalambay fight as counter-evidence, oh how far you have fallen. That leaves just the Tate fight. Tate was not in Canelo's league.
A prime Nunn had the natural ability, which could more than afford him a moment or two of distraction against Canelo - who, whilst a very solid boxer, is not particularly sophisticated. I don't think Canelo has enough to overcome the speed, movement and ranginess of Nunn, even if Nunn were to get complacent.
Alvarez hasn't fought anyone CLOSE to the total package of height, reach, speed, and ability, of Nunn . Factor in him being a south paw on top of all that, theirs very little chance Canelo would take the chance to be great and even get in the ring with him. If he did Nunn would dominate him, possibly embarrass him.
I know that Nunn is Jesus around here, but Canelo is more than capable of holding his own. Canelo would bring the body attack that James Toney didn't. I see a close decision either way at 160 and Canelo stopping him late at 168.
Canelo’s PED’s and judges could make it interesting but it’s a bad style match for him. I think Nunn would win a comfortable decision.
