No trick missed. He was a fantastic player and may become a fantastic coach but eighteen months at one club is not enough to make him that yet. More experience from a second (and perhaps a third club) will only add to his vast experience and teach him stuff he will not yet know. Then he'll be head coach when just into his forties. Still young enough to actively take part in drills and training, still recent enough in players' memories to command respect and with twenty years playing and half a dozen years coaching knowledge.
If he were to come to Saints now, he would no doubt be exposed to plenty of stuff that he has already experienced from playing here, notwithstanding the couple of coaching changes since he left. I also have a thought that he wouldn't be Nathan Brown's type of assistant and add to that that his arrival would go some way to undermining Brown at a time when Brown's tasks are becoming more and more difficult.
He will be back at Saints before 2018
