No, Wednesday was not the best of nights for Heat point guards. Mario Chalmers shot 1 of 9, which did not seem to surprise anyone. Mike Bibby committed six turnovers. When asked about the play of his point guards, Erik Spoelstra danced around the issue after Thursday's practice. "I think we were all out of rhythm offensively, because they did such a good job taking away the paint," he said. Asked about Bibby's uncharacteristic turnover total, Spoelstra said, "Some of those fouls for Mike were screening fouls, and he is one of our better screeners, so we want to continue for him to do that." So that's where we stand. The Heat have a point guard who sets some pretty darned good screens. Or, as we've sensed for most of the season . . . the Heat have no point guard. To a degree, Bibby is what Eddy Curry would become: A potential answer who is not a true answer at all. Bibby closed Wednesday's loss at minus-9 in plus-minus. Chalmers finished at plus-4. And, yes, we appreciate how such numbers can be meaningless when LeBron James ended at a team-worst minus-10.
