Kyle Singler admitted on Saturday that he hasn't been playing with sufficient energy, but he felt better after posting 12 points and five rebounds vs. Miami on Friday. Singler's numbers vs. the Heat aren't impressive, but he made plays when it mattered and sparked an improbable comeback win for Detroit. He was solid for much of November, when he made 50 percent of his FGs and shot 42 percent from downtown, but he's collapsed in December with just 7.6 points on 36 percent shooting, including 28 percent from downtown. He's still playing 30 minutes per game so we'll keep an eye on him.
