Perhaps they were asked to play since there aren't that many teams in the West? And, if I'm not mistaken, the Gulls are an AHL team... so them being there doesn't even make sense to begin. Their 07 BB teams wouldn't be competitive, so perhaps they figured "what the heck."
And to be fair, the Jr. Kings did just sent their PWAA 06/05 team to the Drew Doughty London Jr Knights tournament and put them in the 06 Major division... even though half their team are 05s.
