Saturday's Cotto-Margarito rematch at the remodeled Garden offers the backdrop of bad blood (Cotto lost in 11 rounds in 2008) and a lingering controversy the revocation of Margarito's boxing license in California after a sticky substance was found on the hand wraps he used in a 2009 fight with Shane Mosley.
So, whether or not you knew about that tiny shake or jitter in your hand, you may soon make use of it to replace that old password scribbled on that aging yellow sticky note.
