Not to be confused with the Boston Celtics, the Original Celtics were a "barnstorming professional basketball team in the 1920s," as Wikipedia describes them.
They were one of the most dominant teams of their era. And, after watching this video, it's easy to see why. Popovich-esque offensive execution with that Pivot Play, high-flying shotblocking, fundamental corner jumpshooting -- these guys were ahead of their time.
And we don't talk much about Joe Lapchick as one of the all-time defenders in basketball history. But after seeing his flawless rejection here, I think we all need to reconsider.
