Something that I think would be worth tracking over the last 20 games of the year is points in the paint, both scored and allowed. That seems to be a pretty good indicator of the effort that the Cavs put out on a nightly basis, and I'd imagine a pretty good predictor of W's and L's.
Ever since the Lakers game in LA, the Cavs have really wilted when they've been attacked in the paint, and similarly shied away from driving the ball to the lane on the offensive end. Yao torched us in Houston, the Lakers got over on us in the paint in Cleveland, Leon Powe and friends dumptrucked us in the lane in Boston...I'd even go so far as to say that the Clips gave us the business in the paint.
The painted area is and will continue to be the key for the Cavs. If you've got time, Cavsblogger, I'd be psyched to see that data.
