Surprised it took 5 pages for someone to express their desire for dynamic crowds. If you're going to introduce concession pricing and owner morale, that should go hand-in-hand with what kind of crowd you draw on a nightly basis.
And I agree with what others have said regarding the ability to promote assistant coaches and for assistant coaches on expiring contracts to be entered in a pool of coaches that may be hired both as an assistant or a head coach (for any team).
I'd also love to hear anything about the draft and free agent bidding. Those are incredibly important pieces to any franchise mode.
