If we're gonna talk about boxing, the biggest weakness I see is...

Cotto's inability to defend against the uppercut. Each fighter has made adjustments throughout their career and each has adapted to a new style after they moved up in weightclass. One thing that has stayed the same through each fight is that Cotto has always been open for the uppercut and has been hit hard with that punch. Manny has been vulnerable to counterpunching which is another weakness but has adapted to bigger hitting comp and most of his lapses took place at smaller weights. What is the biggest weakness you see?
