I don't think Link is any chance. Jones, if we could afford him (which we can't) has a funny sort of record. He started well with the Wallabies, then all turned to shit, as it has done with England, and the less said about his stint with the Reds the better. Cron has been successful at the lower tier, but hasn't had a HC role at this level. Probably a good option, but a bit of a gamble. Cheika, if he was interested (and I've seen nothing to suggest he is) would probably be the ideal fit. His record with Leinster, the Tahs and the Wallabies would suggest he's very good at picking up a team that's down and lifting them, but after that he needs to move on. Bears a strong resemblance to the Tahs situation.
