Why was Rumble able to do to Teixeira what Santos could not?

[Talon81]

Would that also make him the hardest hitting welterweight and hardest hitting middleweight?

No, he did not perform at the same level at those weight classes.

War Rumble!
War Santos
War Glover

When Rumble connect you either get really hurt or K.O

DC who fought at hevyweight sad he have never faced anyone thats hit hard like Rumble. Cant wait for Rumble to come back and win the belt.

Technique. Santos has power but he’s very wild. Rumble kept it very basics and just touched him with the uppercut. It was lights out.

 

[TheVenom]

Rumble has a .50 cal for fists

Glover fighting like an idiot against Rumble also helped.
