Apologies for the belated responses.
I strongly dislike this proposal (and not because I slogged through carrying Mirotic in past seasons --- and got a kick out of posting "Mirotic is my empty roster spot" for what seems like 2 years straight).
I think drafting/holding/adding an overseas player/injured player is one of those "tough" decisions owners have to make. In one of the leagues, can't remember which one, I got Mirotic relatively cheaply from an owner because he didn't want to devote a roster spot. I accepted the harm to my roster for the long term benefit.
For what it's worth YH a majority of managers probably agree with you. I'm just of the opinion that the more competitive match ups the better. Add an N/A player to a second tier team's roster and over the course of the season they'll lose a lot more weeks in 3-8 or 2-9 fashion. I'm also opposed to penalizing the rare lottery team that find itself in position to draft a highly rated foreign prospect signed overseas: a Rubio or Saric. I'd prefer those selections be straight forward assets as they are in the NBA rather than a full season commitment to rebuilding.
Now two consolations, though I'm not sure either will change your mind.
Additionally, those unsigned euro's typically provide some intrigue/interest in those top waiver spots when they are unowned and coming into the free agent pool. Sometimes those work out. Sometimes they don't (think I used #1 or #2 on Alexey Shved --- lol).
I for one am bummed on the abrupt end of Shved's NBA career... Anyway, we wouldn't necessarily lose the wavier wire intrigue surrounding veteran international players coming to the NBA. We could handle the reserve spot a couple of different ways. I'd previously suggested that we restrict eligibility to currently rostered players and future draftees. That said, it might be fun to hold a one round draft where each manager could either re-commit to holding a injured player or foreign prospect or lay claim to a player overseas that may or may not be headed to the NBA in the near future.
Finally, the inclusion of "inj" further depletes the already weak free agent pool.
This is my own primary concern, and I'd address it by eliminating the Utility spot. Admittedly, this would be the most dramatic format change in the H2H league's run. Founding manager to founding manager, I'd respect your opposition, but here's my argument. Less than half of the current league participated in the points league draft that kicked off this insanity or had any input into this league's set up the following summer. That, and the NBA itself often enacts similarly significant changes - rules changes, expanding roster sizes, moving the three point line, restructuring divisions.
