Turner is out, who is available?

Re Scott Peters - they seem to prefer the younger coaches: Ben Martin, Robert Livingstone, Jordan Kovacs, Dan Pitcher etc are all staying and the likes of Bob Bicknell, Jim Turner, Jemal Singleton all departing.

Is it as simple as preferring a younger, more analytically driven generation of coaches with the old school who grew up with a more hard-nosed approach (both Singleton and Turner are ex-armed forces)?
