Well, the Scrooge McDuck quote is mine...
But, why are we talking about practice man? Facilities could serve many purposes and probably most of those would cost money. Medical facilities, fan related facilities, training facilities, whatnot...
For example:
Clinic: add 1 level to your doctors skill
Fan Center: add 1 level to your PR guy
and so on... You could add expansions that add the festure skills, for example you add a Social Media manager to the Fan center, who grants your PR guy the nationwide attention or how it is called skill. Cheerteam for the home game bonus...
