Well Sage certainly isn't the best fighter but he does probably have the best abs!
I am a big fan but his dad is fucking up his career by being overbearing and preventing him from training properly at a proper camp. His management, which is possibly his dad as well, is not managing his career very well either so it's a big concern actually for a young fighter with so much talent. Sage also seems like he is too naive and too nice to really look out for himself either so it's actually quite concerning.
In a more professional established sport, an idiot father wouldn't be able to really hurt a young athlete's career so much as there would be plenty of professional college coaches and programs forcing best practices onto the athlete. But in MMA, it's still so new that a kid's dad can just think "i'll train him myself" and no one thinks too much of it.
