Is there an ex player, or soon-to-be-ex player (Not a clue why Dan Biggar comes to mind, but he's a really combative guy, for sure, and he's starting to branch out into different coaching fields) who can step up and be backed for a couple of seasons?
I suspect that the problems go too deep for an ex player to fix. If someone with Gatland's long and deep rugby experience can't seem to do anything at all I doubt if an ex-player with no real coaching or managerial experience would do better.
