I'm pretty sure Ibeabuchi had never been down, but what about Eddie Chambers? I don't think he's been down either.
Over 30 fights and has never been knocked down, and has faced some good punchers. There have been guy's with good chins who have been knocked down by tomato cans like Trinidad, Pavlik, and Pacquiao. It's not like he has only had 20-25 fights and hasn't tasted the canvas, he's had atleast 36 fights has had his chin tested and has never gone down. He deserves to be on this list. Arthur Abraham and Vitali Klichsko are other's who deserve to be on the list.
Arthur Abraham, Joshua Clottey.... wat about Carlos Baldomir~?? I was gonna say Mikkel Kessler but he's been said... Juan Urango~??
Vitali was mentioned. Wright has tasted canvas in the Vasquez fight enough for the rest of his career.
