Since when has great skill ever beaten great skill with size on any regular basis in combat sports? Size doesn't matter as much when you are Fedor(Tyson) fighting bums off the street but when you start ******* with people that know how to throw down Fedor/Bigfoot(Tyson/Lewis) happens. Bones will be the favorite over the sports GOAT if the fight happens and he should be along with his size and age advantages the guy is the greatest LHW champion of all time.
Jones is not in Silva's league, nor has Jones fought someone in Silva's league. Silva has without doubt far superior striking and that alone makes this fight worthwhile. Add in that Silva also is the most dangerous fighter off his back that Jones has fought and that adds in an interesting aspect that might keep Jones from being able to fully utilize his strengths(wrestling and ground and pound).
