There was a rumor floating around that Kid Diamond did the same thing. That was part of the reason Diamond was so hyped back when he was undefeated.
One time, a poster here PM'ed me how he saw Lacy get tooled and run away from Wild Card from sparring there, and he told me he was betting the farm on Jeff's opponent when he fought for a title. I don't doubt that Jeff had problems (he had eye swelling issues at the time) but seeing ONE incident as a predictor of performance is riddiculous.
