I haven't seen this reported anywhere, but there's an incredibly tight race for best winning percentage of all time going on. We all know that the Celtics have the most wins ever, but for a long time the Spurs have had the best winning percentage thanks to Pop having been the coach for half of the franchise's existence. However, with their fall-off last year and tanking this year, they are now #2 behind the Lakers by the smallest of amounts (.000156). However, our beloved Celtics are right there with them, only .000225 behind San Antonio and .000381 behind the Lakers.
In fact, it is so close that it's possible that we take over 1st place on Tuesday in LA! We would have to sweep the rest of our road trip, while the Lakers would need to lose their next three games (including to us) while the Spurs would need to go 1-2 (or worse). The Lakers play at Philly and at Detroit before returning to LA to host the Celtics. Those aren't guaranteed losses, but neither are they guaranteed wins. Meanwhile, the Spurs host Houston tonight, and then visit Miami and Cleveland. It would be very surprising if the Spurs won two of three. We, of course, would need to beat the Warriors and Clippers on the road before taking care of the Lakers, but as well as the team is playing, this is achieavable.
Anyway, this is something to watch -- the Celtics should have the all-time wining percentage lead sooner than later, but it would be pretty fun to take it from the Lakers in person on Tuesday!
