Forum:HOW THE FUDGE IS SAVAGE COLOSSEUM SUPPOSED TO WORK?

Okay, Savage Colosseum says that all monsters must attack, if able. Can you simply switch your monsters to defense position to avoid attacking? And what about Total Defense Shogun, who can declare an attack while in defense position? If Negate Attack stops his attack while he's in defense position, does he survive Savage Colosseum's effect? Can he even BE in defense position? Help!
