This will backfire on him... Sadam Ali is a good boxer. Shaky chin, but he's a better boxer than Cotto. I smell an upset.
Ali has got fast hands & feet but he's brittle & can't punch. I wouldn't call him a "good boxer" if we're talking pure technique, either—makes basic mistakes like lifting his rear foot when following through on a cross.
Cotto would have had to have lost several steps to lose to Ali. It's possible, but if it happens it'll be 'cos Ali uses his younger engine & his quick feet.
