Being an assistant coach at an underachieving club (which saints have been since he's been involved) does not automatically qualify you for the head coaches position, whether you are supremely respected by the players/fans or not. As everyone knows, respect takes years to earn but that can be lost very quickly if he doesnt have the tactical and man management skills needed to manage a successful group of players.
At saints, it is clear he has a job for as long as he wants it, but I would like to see him serve his time under a couple of other experienced coaches (to learn different styles) and then maybe even go out on duel reg to coach a lower division club for a few seasons before being given the chance. We all saw what happened to Daryll Powell when he was given the Leeds job too early, he ended up leaving and spent years learning how to be a coach before then being given the opportunity again in SL. Hes now considered strongly to be coach of the year. Exactly the same happened with James Lowes when he was at Warrington. Sometimes, the legacy as a player and reputation as a person clouds the fact that you may not actually be the man for the job at that specific time.
Im sure KC will go on to be a successful coach, no doubt, but I just worry that being given the job too soon may do him more harm than good in the long term.
