As was noted on the "Dunc'd On" Podcast by Nate Duncan and Danny Leroux noted that the Celts are currently forcing almost 19 turnovers a game, which is almost 2 turnovers ahead of the next best team. That doesn't seem sustainable.
The schedule has been mixed so far -- the Celts have played some quality offensive opponents like the Raptors, Hawks, and Spurs (and the Thunder, though without Durant), but also played some really poor opponents like the Pacers, Sixers, and Nets.
I'm interested to see if the Celts can keep forcing lots of turnovers, and how they'll do as they face more quality offensive teams.
