I don't think Ibeabuchi needs to be technical with Norton and simply blitzes him in the opening rounds.
Just too little data. Yeah, Norton struggled against punchers, but Ike never fought a quality guy who was 6'3". I always wonder why the Grant fight never materialized. Was there something in that swarmer style that needed a physical advantage? I don't know.
Norton way more skilled but he tended to stand in front of dudes and fight them head on. Not sure that Ike is the right guy to do that with.
I think Ibeabuchi's pressure would have overcome Norton's defense and Ken's jaw would not have been able to withstand the power of The President, so I say Ibeabuchi by TKO before the 10th round.
Ibeabuchi screwed up before we truly knew more about him, but I'll go with him by KO over Norton. Norton didn't do well when faced with big punchers.
