The Washington Wizards are 26-20. As has been noted widely and with tentative enthusiasm, Washington has the best record in the East since December 1, at 20-9. And with their best performance of the season occurring just days ago in Atlanta, the line is still trending upward. With a broad stroke, it’s easy to see a few reasons for the shift in efficacy: a coach that experimented desperately for weeks at the season’s outset finally settling on rotations that emphasize the presence of multiple starters on the court at most, if not all, times; Bradley Beal finding a comfortable mix of ball-handling and catch-and-shoot opportunities, driving to the rim more frequently in the process; Otto Porter shooting the lights out from behind the arc.
