Scott Coker must love the fact that the only guys calling eachother out are guys in different weight classes. They'd love for 2 guys in the same division to call eachother out for once. I'd be very surprised if Mayhem-Diaz, Daley-Noons, Melendez-Noons or Diaz-Jacare ever happened. Just set Diaz vs Daley up, least once Daley knocks Diaz out Nick'll be keener to fight Mayhem, though after that the money making potential of the fight drops significantly. Not the best situation for Strikeforce really.
