He has a balanced team, plus outside offense doesn't need that much of the inside players like the inside offense needs the outside. You can't just play with 3 centers and expect it to win because you put up a sensational in inside offense, but now one good enough to provide for that good of an attack. You need to have 2 good guards with good passing and a SF that's NOT a Center.
One player with passing is not enough. Not when you have an inside offense of prominent. But the SF, may not be bad in OD, but I don't think that he has enough passing to be effective in the offense ;)
