Overhand Right: The most effective knockout technique in MMA? (HD)

The overhand right seems to be the weapon of choice for many MMA fighters today, and this is surprising because it is not generally considered a sound boxing technique. This highlight video has clips from UFC, pride and other organizations. It features Roy Nelson, Dan Henderson Rashad Evans and other power punchers. Also, I am aware some of the clips are not overhand rights (Hendricks).
