Lennox would have beaten Ike.

When I watched the Byrd fight I saw Ike getting frustrated and condoning to swinging for the fences(until he finally landed one) he also got hit a lot.

And despite how hard Tua hit, I think Lennox hit harder just on his size and his ability to use it, his jab was enough to frustrate Ike.

I think Ike had all the talent in the world, but not the mentality to hold the championship, he would have broken down mentally eventually. It just would have been about 5 more fights down the road in my opinion.
