Was about to mention Bones, because he's got some thin/skinny calves (and quads).
I'm telling you, if you're a half decent coach and if your fighter is going to fight Jones, have him train leg kicks and defense 24/7.
I till can't fucking understand how, to this day, people can't put two and two together: Small legs/calves + hard kick = trouble. The reason is simple: the knee has bones that are twice as hard as the shin. If you hit the bottom part of the femur or the top of the tibia with the shin, you're asking for trouble, especially if you are Silva or Jones.
I'm telling you Jones is next.
