So many of Whitaker's fights could be considered this. My personal favourite is Winky-Trinidad. Winky had an ability to really show people up. I'm also going to throw in Darchinyan-Mijares.....just to point out that you don't have to be the technically better boxer to school someone.
definately the one that stands out in my mind was Calzaghe v Lacy...it was all the more memorable because many of the boxing press were saying Lacy was going to KO Joe...then we got what we saw!
