I would like a couple of extra teams to come in,
it would give more opportunities for the guys who return home from college, better opportunites for guys who do well at SEABL/ABA/NZBL level to make a 10 man roster,
give better oportunities for guys like Rhys Carter, Daniel Dillon to stay in the NBL as starters and earn better $$$ in Australia, and if you can bring guys like Neville and Worthington back into the league and promote a couple of guys from benches at other teams to starting on a new team eg Wagstaff or Creek.
If it comes to a point where the Australian talent is too thin as too many top players are overseas, just allow clubs to 3 imports, even if the 3rd is a Massingale type out of the SEABL/NZBL, which would also be great for the imports who star in those leagues and would help them attract stronger imports as they would have a better pathway to the NBL.
I think a team of
Neville, Worthington, Carter, Dillon, a top 6th man or 2 from other clubs eg.Wagstaff and/or Creek, 2 imports, 1 or 2 decent college returnees, and a top SEABL/NZBL player would be a competitive team from the start and not totally unrealistic within the salary cap, etc.
It may also mean guys like Ben Dowdell, etc stay with Basketball and could prove to be decent NBL players over time if given the right opportunity.
