Kassim Ouma - tough fight for GGG Curtis Stevens - another tough fight for GGG Osumanu Adama - he gave GGG some good rounds. Top 10 ranked MW's like Macklin, Geale and Rubio got knocked out by GGG. thoughts
Stevens and Adama didn't win a round off of Golovkin. Ouma did but that was a while back. The two best opponents he faced, the only ones I ranked in the top 10 heading in and that could be described as "top tier," are Geale and Macklin and he scored epic KO3's over each.
Seems like every time GGG has a "real test" against a "legit MW" he blows them out in about 3 rounds.
GGG walks through Canelo in 5 rounds or less. Ward and Froch are potential problems. Styles make fights and some unknown contenders are better than the name guys.
