Ray Mercer did about as concussive job on Morrison as I've seen.

And funny enough Mercer wasn't known as a puncher which is even more scary.

Ernie Shavers for me.
Big George, Julian Jackson, G-Man, Nigel Benn, Naseem Hamed, Archie Moore and Bob Foster spring to mind.

A testement to Mercers anvil hard head,Morrison actually power boxed pretty well and in the 3rd he landed an uppercut followed by a left hook that would have demolished most heavyweights at that time.....strong and fast,Mercer got that wincing big eyed look and stayed up right and soon returned the brutailty in kind....just crushed Morrison like an empty Dixie Cup
