Right now? "Cassius" Clay Collard of course!! Haha kid has heart. I like the "let's just throw down" mentality. But to be honest, I like to many boxers to pick a number 1.
Tough to say it isn't Loma, but he's getting up there in years and hasn't been in a huge fight in a while.
Favourite as in, who I follow and care most about winning/losing: Carl Frampton Favourite as in, love the guy's style, personality, think they're a great champion and want to see them win, second only to Frampton: Tyson Fury Favourite as in, to watch box: Vasiliy Lomachenko
Ted Cheesman because he's got a great attitude and I love how he fights. Srisaket Sor Rungvisai because his story is inspirational and he fights like every fight like he's still starving. Juan Francisco Estrada because he genuinely wants to fight everyone, and doesn't seem to give two shits about the money.
Tyson Fury - I just find everything about him, both in and out the ring, utterly compelling. Beyond that there are a number of young, up and coming fighters that I support. Some like Vergil Ortiz Jr and David Benavidez are likely destined for greatness. Others like Denis McCann and John Docherty may or may not go far, but I love their attitude. I know he's not everyone's cup of tea but I love watching Sunny Edwards box, plus he seems like a good lad. Same with Brad Foster who someone's mentioned up thread, a good honest kid who's working hard on his game and making big strides.
Danny Jacobs and Lomachenko I'll add on John Ryder, Usyk, Chisora, Hunter, Shawn Porter and Joe Smith Jr.
Adrien Broner should've been a comedian I like hearing him chat **** more than I like watching him fight, kinda like Billy Joe.
