People who talk about Rory as some kind of PR ambassador forget that he would use such a position to promote his religious beliefs, which, while I will never criticise someone else's path to God, might not be the image we want.
Look if there is even the slightest chance we can get God on our side its a win for us.
From what I've seen God is not just a good motivator/positive presence in the dressing room, but can play in pretty much any position in the universe and because he/she/it is God then he/she/it will not take up an import slot, being god and all.
Once we get God in the Squad, (sorry), then he can open the door to the agents of other deities such as Thor, (great right foot), Kali, (great goalie) and Satan - ok he dives a bit but can put it away.
If we can get God and say Thor and or Shane Smeltz or the Great Beast, (no not Lia), then we we get an end product for Ernie's grand plan. Kali back up for Mossy - we win.
