Are you serious ? First of all , Bellew was a cruiserweight and not a LHW. Second , he didn't really knocked him down and only won because David was injured. And third , no LHW could beat a David Haye in top condition , absolutely no one.
Bellew is a natural LHW. He knocked down Haye twice, once through the ropes. David Haye in top condition seems like a myth. Haye would, could and should but he never did. Fact is, Bellew won most of the rounds before the infury. I remember these sweet counterpunches.
You didn't watch the fight , David Haye won 4 of 5 rounds before the injury and won even a round with one leg. And this is a fact. Prime David Haye would beat all of the cruiserweights today , he was one of the most powerful punchers in the HW division and at cruiserweight , he was maybe the most powerful puncher of all time.
And Bellew is not a natural LHW , he struggled to make the weight and was drained in his most fights. He is a natural cruiserweight.
Bellew was scared in the ring against Haye , he was running for the first 5 rounds , there were no "sweet" counterpunches. He lost 4 rounds out of 5 . You can clearly see , that in the moment he had seen that Haye was injured , he started to throw punches. Bellew wrote a will before the fight ( i'm not joking, he really did ) , he was scared to death. He was only in the ring to survive and everybody , who tells otherwise , didn't see this fight.
Look at all the haters in this thread. Bellew is p4p top 7/8 in the world right now. Haters gonna hate.
