I think Bennett's plans moving forward may be similar to what he's doing at Souths now.
Come in as a senior coach for a couple years with the intention of an assistant taking over.
It's what he proposed to the Broncos board for him with JD, and it's what is happening at souths. There were also reports of the dogs making an approach to Bennett coming in with Ennis as an assistant and eventually taking over.
It makes sense for Bennett to come in as a guy that can right the ship, get the football department setup with pathway systems and oversee development of a new head coach.
Kind of like a 2yr consultancy at the club to get them setup and on the right track before moving to the next.
You would probably just look to limit his involvement in recruitment and retention, given he wont have a long stay at the club, but other than that he could be a good option to get things moving whilst providing instant credibility to a club
