A: This has been one more of the more cogent missives when it has come to Derrick Williams' absence from the Heat's regular-season rotation. And I would add another name, that of Josh Richardson. Erik Spoelstra has long been cognizant of lineup combinations, which players work best together. Add Ellington, McRoberts and Richardson, and suddenly an athletic presence to get the defense on its heels makes all the sense in the world. But until McRoberts, Ellington and Richardson get back, the Heat have to at least present the threat of 3-point shooting. This is not a case of Spoelstra saying that Williams is an ill fit, an end-of-the-bench presence. I think those conclusions totally miss the point. This is Spoelstra, in my view, finding it difficult to explore all of his roster possibilities without a complete roster.
