Just to play devil's advocate:

Taylor - Pavlik already stopped him. 160 was his best weight class.
Abraham - Dirrell already beat him. 160 was his best weight class.
Pascal - Great Win. 175 is his best weight class though.
Bute - Froch's best win.
Kessler - Good win. Splits series with Kessler. 31 year old Kessler beat Froch in a close fight. 34 year old Kessler lost to Froch in close fight. Age play a role?
Dirrell - Close fight. Counts as a win though.
