My strategy, especially when we have Ray Allen in there, is to play a lot of zone. This congests the paint, protects Allen, and forces them to beat us from the outside.
I also would like to see Sasha on James. Quietly, and in limited opportunities, I've seen him do a good job on him, which probably has a lot to do with him knowing his tendencies well from playing with him for 5 full seasons in Cleveland.
I've also seen Daniels be effective against Wade when posting up offensively. Plus, since Wade likes to gamble in the passing lanes Daniels' quality movement without the ball game could be used for some easy baskets.
