I still think small forwards are the key, they are the balance of the game. (or the unbalance in this case)
But while driving inside forwards are really cheap, shooting or spread the floor small forwards are very expensive. Also on the other end of the floor, Inside defense is also very expensive for small forwards. You see good inside teams with 3 mayor offensive players in C, PF and SF being the latter significantly cheaper. But that becomes really imposible for outside teams as outside based SF are very expensive.
If you change SF formula to make JS cheaper and IS as important as JS for the formula, suddenly you get an even playing field.
