Matthew Hatton..

He looks ridiculous, like Sloth from the Goonies. His lack of talent is surpassed only by his lack of charisma. He's a mediocre example of mediocrity.

Yet when he was hired by HBO to be the highlight reel KO to bring Canelo Alvarez to the big stage he apparently forgot to read the script and actually fought to win. He lost near every round but in the face of hopelessness he kept his belief and determination, and after the fight just merely shrugged and said he would move back down to his natural weight class and fight for a world title there.

Self delusion of course, but I admired his optimism and never say quit mentally.
