A tough one but I'll take a crack.
He's a phoney bastard who may as well have bought his brown belt from primark. He consistently produces terrible fighters who have no idea what BJJ even stands for far less how to do it.
Why does the Carluke bullshitter get hung out to dry when it's common knowledge that Amro is a complete fake? Good judo = yes. Brown belt in BJJ = absolutely preposterous.
