that should set up:

mosley vs floyd

cotto vs hatton

results will be:

mosley knocks out floyd

cotto u.d hatton

than that will set up:

cotto vs williams

that sets up:

cotto margarito

results will be:

that sets up:

margarito williams 2

margarito wins u.d

than mosley margarito for the finale.
