Now that players can get an additional stipend, people won't raise their eyebrows quite as much when a player seems to have a little "more" in their lives than usual. So when they get those "extra" contributions from boosters, it may be a little easier to mask what is going on.
So boosters, when you do this, don't buy the player a Ferrari, that is a bit too noticeable. Play it smart and just get a Corolla or something like that.
