Tuesday night on TNT has a lot of superstar power on tonight's doubleheader.  First you have the Lakers and Cavaliers.  Always a good matchup when LeBron takes on Cleveland.  The Lakers have been playing great lately too so that game might be surprising.  The Cavs are favored to win by 5.5.  Then you have the Nuggets and the Mavericks.  The Mavs just played yesterday against the Suns and that's a pretty intense matchup so I'm guessing they may be a step slow today.  With the Nuggets also 5.5 point favorites I think everyone else is expecting them to win also.  Gametime in about 45 minutes.
