Interested to know who you'd be keen on and could possibly get.
Macqueen hadn't coached for 8-10years and was more a name. Hill had spent time in Japan but only a season under Macqueen in a super rugby program, McGahan reasonably successful run with Munster but not so great with the Wallabies, Wessels assistant to an unsuccessful force program with Foote, then HC for an unsuccessful program (with Foote as an assistant) then moved over to Melbourne for another three odd seasons of mediocrity with Foote as an assistant.
Current Super Rugby assistants worth looking at McKay or Gilmore (Fisher said he doesn't want a HC role). Aussies abroad in MLR, Hoiles (LA) and Gerrard (Austin) probably too green. Andy Friend at Connacht would be a goer. Les Kiss at London Irish maybe. Plenty of professional experience in Shute Shield with guys like Barakat, Blake, Hedger, Louden and Melrose. Current 7s Manenti or Walsh. Could go outside the box and go for someone like Mick Heenan who surely would have had plenty of professional offers (maybe just not HC ones).
I'm sure there are a few more I would have missed.
