Well you do when you said you guarantee.I didn't think I needed to make an exception for 3 players out of 46. The way Leniu was bitching about match payments I'd wager he would ditch Samoa to play for Australia given the chance. Batman is a mercenary so I wouldn't put it past him either.
Allowing internationals to be eligible for Origin now makes a farce of SOO and international representative duty as well.
Tongan, Samoan and Fiji reps etc have always been eligible for Origin (if they met the resident before 13 rule).
