Why do you see that as unfair?
You just could make your investments a little later. Now you had the money to improve your team just before the playoffs because of you late tv-games. Maybe I find that unfair? (I don't ;)
I do think this will even out, since everyone will most likely just invest at another point in the season, but at the end of the season everyone has the same amount of money recieved from TV-games.
