Of those touted to be in the frame, I'd be fine with Schmidt or Worsel. I could see Howley working under Dai, but not as DoR. Neither Lancaster, nor o'Shea are right for the club at this time. Blackett will live or die on results over the next few weeks. On yesterday's performance, he's pretty much DOA to my mind. I'm undecided on Cockerill, maybe too long an adversary. Just please all the powers that be, not Cheika. I couldn't live with that.
As for the rest of the coaching set-up, it would be good to have the continuity that Titterall brings, and the connection with the club's history that Kinga or Walder have. That said, LBND has no credentials. I'm always wary of spillover credibility. Great captain and club stalwart, but not as DoR (remember Martin Johnson as England Head Coach).
