Fedor: Sambo and Judo
Fedor could be included in the thread if we're talking about any two Combat Sports.
jones is not an elite striker and would get killed in k1 and boxing
he would get ragdolled by any olympic wressler
he would get tapped by a guy like Estima or Drysdale in under 1 minute.
And btw i like Jones, he's the lhw goat but mma is an ocean of knowledge with few inches of depth. If you pick just one discipline, it's a deep ass pool.
People aren't assuming Jones would just go there and succeed, if Jones trained specifically for any of those sports he'd have potential to do well.
