I remember few months back Rich Franklin fought Ken Shamrock.
Franklin/Silva are in same class.
and b/c Shamrock and Franklin fought
Franklin/Silva/Shamrock must be in same class.
Shamrock fought Ortiz for title therefore
Franklin/Silva/Shamrock/Ortiz must be in same class
Ortiz fought Liddel, there..
Franklin/Silva/Shamrock/Ortiz/Liddel must be in same class
Will Silva/Liddel ever fight?
