Those things sound a bit sim-cityish but the training facilities might be a good idea- have several levels of training facilities that can be reached depending on the amount of cahs you sink into them and make it a multiplier to the training.
1- dank costs $10000 up to 7. state of the art- costs 7.5 million (roughly the cost of a maxed out arena)
Once you pump enough money into ti your training facility goes up to the next level
dank
smelly
free weights
nautilus
air-condfitioned
full fitness
state of the art
or something like that.
I also like the idea of having some kind of promotional package that may or not bring more merch sales or seat revenue.
Once I scored a basket that still makes me laugh.
