It will come down to who he surrounds himself with moreso than the playing group. He needs to NOT surround himself with mates on the coaching staff as I see that as more of an issue than having played with a few of the team i.e. Black, Brown, Power, Notting, Copeland. His first job may very weel be cutting the likes of Notting and Copeland, and Matthews will still be around to give guidance with the season review via recommendations.
As for him jumping around, Coast wouldn't offer him a long-term deal like he had wanted, Weagles no problems Leigh leaving wasn't on the agenda then so he was going to get some experience. As for experience well his few years in the media will help as he has been analysising games for TV as the games is on so whilst not that same pressures gives him a leg up.
But going back his off-field team is the important one, for mine he can't have the Leppitsch's and Hart's and Lambert's as assistants, that is where the new blood is needed IMHO.
