Marco Antonio Barrera vs. Johnny Tapia comes to mind. Tapia lost compehensively on points but he gave it everything he had and made the fight interesting right to the final bell. Also, the first Morales vs. Paquiao fight where Morales battered Manny but the Pacman would come storming right back every time. Not a one-sided fight, but at the same time Pacquiao never looked like he could win it.
Maybe "one-sided" is extreme, but I had Ali beating Foreman handily in Zaire before he stopped him. He pretty much out-fought him all night long, even before Foreman fatigued.
calzaghe's humiliation of jeff lacy was a thing of beauty i thought . anyone who disnisses that win without taking into account the masterclass joe put on is a joke. jones jnr v toney, lovely to see the mouth that is james toney pretty much humiliated
