From the one's you listed Foster over Tiger is the most brutal for me...


I'd list;
Gatti over Dorin
Louis over Schmelling 2
Patterson over Johansson
Toney over Nunn
Carbajal over Salazar
Tarver over RJJ
Takaloo over Alexander
Ike over Byrd
Cooney over Norton
Morrison over Ruddock
Ward over Sanchez
Curry over McCrory - Didn't end the fight but what a hook.

Of recent times;
Peter over Williams
AA over Khoren
Bute over Andrade & Miranda
Brock over Zuri
