Firstly, drafts are basically illegal in Australia.
I agree with the concept of a Next-Stars draft, and it could work because the players would be contracted with the League, not individual clubs. Hence it wouldn't be a draft in the usual meaning, but simply a mechanism for the league to allocate its employees. Guaranteed minutes, etc, could still be attached to individual players and it would be up to clubs whether they choose them.
The whole problem with DPs and TPs, is that it's NOT a guaranteed pathway.
Often these kids have spent 4 years in College, earning a degree in basket-weaving, and by the time they arrive in a DP or TP situation, their dreams are well and truly shattered.
This isn't like the AFL, where a player would eat his own testicle for a Rookie spot. These "otherwise unemployed" ballers need to be looking for their NEW career. If they can then pick up an SBL gig, and/or get asked to be a TP, then that's just a bonus.
I guess some teams are able to make decent offers to DPs, but most teams cant, and I imagine it will dry up even more post-covid.
But either way, the NBL reality is that a Draft for those players would be arse-about backwards. Can you imagine the BEST unsigned prospect in the country being told he has to move interstate and play for the Hawks, pay his own living expenses, whilst earning peanuts?!?
