No. Jones isn't a big name yet, and hasn't defended his belt once. Also, he keeps running away from Rashad.
GSP/Silva
Brock/Cain II
Cain/Overeem
Brock/Overeem
These fights are bigger.
I agree with Silva/GSP. But Brock/Cain II does nothing for me as the first match looked so one sided. I think Overeem is so over rated its not even funny. He has one good win vs Belfort in a fight where belfort was fighting up in weight. Overeem has not looked impressive his last few fights. I would actually put Cain/JDS above the other three as well.
Also Jones name is already big. You don't become a title holder in argueably the toughest division as an unknown. He is quickly becoming the most marketable face in the UFC.
