While I agree that the T. rex may have been too fast, I'd definitely
add a bit of doubt to your definitely.

We've rehashed the "falling T. rex" on this list quite extensively, 
it still does not disqualify T. rex as a high speed carnivore.  
Perhaps they had a mechanism for dealing with a high speed fall 
(twisting to the side, translating the direction of momentum, etc.)  
Perhaps they -simply didn't fall-.  It would be quite easy to 
demonstrate that the rock climbing life style of mountain goats is 
unlikely, as a single slip would result in their crashing to their 
death.  But the goats persist in clinging to their perches.

Falls by a T. rex might have caused injury, but they might have
been such rare events that the need for greater speed outweighed
any threat of rare falls.  It's quite unfair to say that T. rex
couldn't have been so sure-footed simply because we are such
klutzes.  Animals take such extreme chances every day.

T. rex was a predator, and it had to catch its prey.  Unless you
are ready to bog the whole Creatceous in an endothermic slow dance,
I seriously doubt that T. rex would have any trouble outpacing
such a poky creature as a human being.
