If you watched the Miami Heat beat the Los Angeles Clippers Thursday night, you probably noticed that unless Willie Green was defending LeBron James, the MVP wasn't moving all that effectively. Blake Griffin routinely defended him pretty well and James just wasn't very aggressive in how he attacked the Clippers' defense. You also probably noticed when he checked back into the game, they unwrapped heating pads from his back. The reason for the heating pads would be back spasms that he's apparently had for a couple of weeks, according to LeBron after the victory. He said the only way he wouldn't be able to play is if he couldn't get out of bed, but this may be something to track after nearly 300 games the past three seasons.
