Funny you should mention them. Because Silva and GSP are two of the very few UFC fighters that are close to being actual Martial artists.

There are few MMA fighters that are proficient in martial arts and think and act like martial artists.

Not that a martial artists is a singular idea, or that they all would be clones of each other, but there are certain attributes.

Both of them don't talk ****, and if you talk **** about them, they take it as disrespecting them.

But they won't do anything until the right time.
