Golovkin Perfect record, beat every top middleweight except Saunders who has been ducking him, Stevens Murray Brook Jacobs Lemieux Canelo All of them very good fighters with Lemieux, Canelo, Jacobs and Brook being A- at least, Canelo and Jacobs arguably being A+. He dominated the division, almost has the record for most title defenses and his ko streak is incredible. He is still going strong nearing 36, if he beats Saunders and beats Canelo in the rematch he will be hall of fame for sure It was a hard choice between him and Bud
Leaning more towards Crawford. First undisputed champion for years and barely lost a round in doing so. Ring IQ and adaptability off the charts.
