82games.com has their taking charges stats up for this season. It's somewhat interesting.
Jermaine is 7th on the list despite missing quite a few games. Dunleavy is tied for 8th. I think it's safe to say that JO would have led the league had he played the whole season.
Another interesting name to note is Kyle Lowry being #4.
