Diaz/Lawler is the fight to make. Sonnen wrestling Diaz is going to be blue balls for everyone. Sonnen/Mousasi? I would say Tim Kennedy but it seems the UFC have blacklisted him.
Sonnen silva 3 plz. Those two have major chemistry together, and even though they are getting long in the tooth, i think people would tune in. Diaz would be good for the trash talk leading up.
