This is always a recurring topic around groups of people when Floyd Mayweather's name comes up or when at a fight party. "Shane had him, he HAD him"

It seemed as if Mosley was even taken aback himself that he got in a shot that clean as effective and just couldn't follow through quickly. To Floyd's credit, he did recover quickly, but those couple seconds Mosley stood there idle under Floyd's clinch (a rather weak and escapable clinch at that) were costly. Real knockout fighters know precisely what to do and what combination/angle of punches to throw when their opponent is hurt....and waste no time in doing so, even if the other guy is holding. You think a guy like Duran would have blown that opportunity?

So the question remains: What should Shane have done exactly to capitalize, if it all possible?

I swift right uppercut wold have been perfect IMO. Floyd's chin was wide open right after he had gotten back into his stance. Who knows how more wobbly he would have been after catching a shot right on the button...
