This is how a Pride v UFC Tourney would play out imo.
Start with the lw Pride would be shocked at the talent in the UFC given the history of Bushido. Pride will also have some top lw's move to WW since they don't have the WW weight class. Pride only wins 3 of 6 fights Kid, gomi and Kawajiri are the only winners. UFC winners are BJ Penn who drops, sherk, and Franca.
WW is dominated by UFC winning 5 of 6 fights. nuff said we all know who fights at WW.
MW gets interesting because it is again split. Franklin, Silva and Dewees winning for the UFC and Filho, kang and Misaki winning for pride- another split.
Chuck tito and renato are the only hopes for the UFC LHW division. Tito loses Pride wins 4-2.
HW is dominated by pride much the same as WW was dominated by UFC. Pride wins this 5-1. Silvia shocks the world and ko's emelianenko. (alexander)again we all know the pride hw's nuff said.
Overall in an extremely exciting and competetive ppv pride takes the pride with them 16-14 final score with the UFC LHW and HW divisions losing a big lead.
