The most encouraging thing for Dallas fans has to be the resuscitation of the Mavs best player. Dirk Nowitzki's awkward fadeaway was starting to look less like a charming trademark of his game, and more like the desperate shot of a 33-year-old who'd lost a step. But during the Mavs recent 6-game winning streak, Nowitzki looked strong and poised, averaging over 23 points per game and scoring 24 in the second half of a road win against Philly.

All season long Dallas has been erratic, interrupting Championship-level play with spontaneous losing streaks. So, we'll see if a heartbreaking loss to the Knicks on Sunday leads to a curious string of L's. If the veteran-saturated Mavs can stay fresh and play consistently in this condensed season, then they'll be going deep into the postseason. —Sean Evans
