"To be clear, Matt Nielsen and Adam Forde both left and looking to replace them the coaches that were approached and all rejected the offer to work for trev are
CJ Bruton
Sam McKinnon
Luc Longley
Mick Downer
Paul Hearne"
Weren't CJ and MacKinnon already part of the Bullets staff, and Henare on the United staff? Longley is a consultant/advisor to the Kings rather than a full-time coach, I think he did that for Perth previously - I seem to recall him working with Brandt.
Guys like Nielsen and Forde pursuing other opportunities isn't that strange. Nielsen probably wanted a head coaching role, but with Gleeson signed for another 3 years it wasn't happening here.
Forde turning down a lead assistant opportunity was interesting, but I can see how the Sydney role is attractive to expand his horizons (still a relatively young coach) and build some NBA connections with Weaver/Pongrass and co.
