Since I archive the projections each day, I can also use Google's Motion Chart API to show how those probabilities have evolved over time. The Lakers, out of all the NBA teams, have had the most ups and downs in their playoff fortunes since the All Star break. Click the play button on the chart below to see that in motion (flash-based, not mobile friendly).
At the All Star break, the Lakers' had a 19% chance of making the playoffs. That percentage has basically flipped, with the Lakers now at an 81% chance of making the playoffs. However, this does not factor in the latest development in the Lakers' season, Kobe Bryant's likely season-ending Achilles injury.
