Winning this series is going to require a constant juggling act from Mavs coach Rick Carlisle: his best offensive unit can’t defend LA, and his best defensive unit can’t score against them. He has to hope Dallas can stay even offensively when Terry and Barea aren’t in the game, and that those two continue to dominate when LA plays their reserve guards — Shannon Brown and Steve Blake. Then in crunch-time, he has to hope that neither Kobe nor Artest can take advantage of the shorter Kidd defensively. At the same time, he has to buy time on the interior when Dirk’s not on the floor, and hope that Shawn Marion can defend Lamar Odom and keep him off the offensive glass, despite giving up over 3 inches in height. If all this goes right, like in Game 1, the Mavs still need to out-execute LA down the stretch to win. Their margin for error is slim at best.
