I would take Mark Gasol. Dwight is the better player, but Gasol would give you 75 to 80% of the stats at half the price, 20% of the ego, 10% of the headache associated with that ego, the technicals and the flying elbows and probably about 1% of the joking when you should be serious and trying to win games.
I did the math and it all works out, trust me.
