Nope, but to be fair the only fighters worth a damn he fought was Tua and Byrd, and the latter is feather fisted (heh, feather, Byrd)
He took Tua's best shots. That tells me right there his chin was very, very solid. Tua was outboxed by safety first Lewis and Bryd. But, Ike stood right in and traded with him. Ike and Tua both had awesome chins and good power. Hence, they engaged in a highly entertaining and competitive affair. Ike was a little less a one trick pony then Tua, thus he was able to get to Byrd and KHTFO. It would have been VERY interesting to see if Lewis could survive the Ike attack. Too bad it didn't happen.
Seems kind of unfair since many other chins are much, much more highly tested yet more lowly regarded than Ibeabuchi's
How is his chin not highly tested. Tua was a limited boxer. But, his power was awesome. Ike took his best without flinching. Your argument is quite spurious. If Lewis traded with Ike, I am confident Lewis is the one more likely to get hurt.
It doesn't take a 100 fights to prove the quality of a fighters ability to take a shot. Sometimes it can take 1, especially if the fighter throwing and landing the punches is a true and proven puncher. Tua was a true and proven puncher. The night he fought Ibeabuchi was the best I ever saw him fight. In my opinion it was Tua's best performance against any pro he faced. Yet, for all the clean punches he landed, and as many punches he landed Ibeabuchi barely blinked. The night Tua faced Ibeabuchi he probably beats most heavyweights of that era. Including Lewis. Ibeabuchi chin was truly world class, as was his ability. It is a damn shame he couldn't control his demons. He had almost every tool to be a dominant champ.
That's highly debatable. Lewis was in a war with the likes of Vitali, Holyfield, and Mercer. All tough ranked guys. Ibeabuchi's list of quality opponents whom he went to war with begins and ends with tua. We know Ike has heart and a good chin but it's hard to favor him when lewis' resume is 10x deeper
