No one’s ever claimed he’s perfect, obviously. But let’s not act like that one incident defines him. Mathieu has been under immense pressure his entire career, especially during the peak of his rivalry with Wout. Half the time it was Mathieu vs an entire nation including fans, media, and commentators, all constantly poking, provoking, and looking for cracks. He’s had beer and even piss thrown at him by deranged fans blinded by hate and envy.
And through all of that, he’s handled himself with more grace than most ever would. If you’re being fair in your assessment, you’d have to admit that compared to a lot of champions, both current and past, he’s actually a role model when it comes to composure and character.
