I expect the NRL will do what they have done in Newcastle - they will establish a Board of local successful business people, and support the club financially until there is enough corporate backing or a new owner to take over the operations of the club.
Aside from all the drama associated with a Nathan Tinkler ownership model, it is now BAU for the Knights, although memberships have continued to slide. I anticipate the opposite up on the GC. A lot of excitement in a post-Searle world.
