Yep, that's the other guy I looked hard at.
Russell and Garnett is quite a defensive tandem to consider. Athletic, crafty, unceasing Energizer bunnies. They will get muscled inside by a small handful of behemoths, but they will also get inside heads and under skin. You definitely haven't left yourself room for a take-over-games-inside-the-paint kind of offensive big man, although there are some interesting post-up options still on the board at other positions. Very interesting pairing...
