Carl Froch
Froch’s last fight against George Groves was a struggle for the WBA super middleweight champion. Groves dominated the fight through the 9 rounds but landed a few good punches in the round to earn a stoppage. Most people thought the stoppage was premature and saved Froch from the loss. With what was shown in that fight GGG would dismantle Froch in the ring. Golovkin is more fundamental than Groves and has 3x the power.
