Am I crazy for thinking Vernon Forrest could win?

The guy is winning fights impressively as of late. Williams wouldn't enjoy a huge advantage in height (though only the heavies can match him in arm length) and Forrest is a guy with KO power as opposed to Williams' last few opponents. Unless I'm mistaken, the only guy who ko'd Forrest was Ricardo Mayorga and Williams doesn't have that kind of power and Forrest won't be that reckless in the future.

Williams should be interested in the fight for the same reason Margarito was the 'most feared' fighter. You can't go around saying no one will fight you if there's a legitimate threat who will.
