You've really got it in for Quade and have huge support for Thorn don't you? Whats done is done. Thorn is now trying to work out who he plays at 10, seemingly having decided Stewart isn't providing what he wants and having had Stewart moving all over the backline during a game, he has now gone with Hegarty. Perhaps he is waiting for McGahan to be fit or maybe Hegarty will deliver, but even then having a big number 8 running at you is hard to combat which is why teams often use that tactic on the 10. It happens.
Quade is playing well generally for the Rebels so good for him, if you select your 10 primarily for their defensive capabilities then you are going to be missing out somewhere else.
