What is your interpretation of the apparently healed bite marks in the
tail of Edmontosaurus and the illium of Triceratops - don't these
suggest that Tyrannosaurus could grapple something and run? OK maybe
it was the Edmontosaurus doing the running in the first instance, but
I do know that if I'd just bitten the back end of a live Triceratops I
wouldn't want to still be there when its front end turned around.

Their teeth and their skull biomechanics. Tyrannosaurs look more like they
took time to place a bite in a convenient position and then thoroughly
crunched their prey. This should kill or at least immobilize most animals up
to the tyrannosaur's own size pretty quickly and with a high success rate,
but looks like an unnecessary risk when the prey is twice as long and tall
as the predator.
