82games.com just released sortable team stats by position for this season, and the numbers are telling. Check out this article on PER Differential by position. The Bulls rank 5th and 4th in PG and SG play with about a +6 differential in each. Larry Hughes' shooting has helped, but Ben Gordon has done the brunt of the good work while stepping up defensively. Our SFs are playing at a -1.3 differential. Our worst production has come from our PFs and Cs, but you might be surprised at just how bad they have been. They rank dead last at PER differential at -7.1 and -7.4 apiece, and it's been a result of mindnumbingly bad defensive play. Per game, opposing PFs are averaging 23 points and 12.1 rebounds with a .512 efg%. Opposing C's average 22.5 points and 14 rebounds with a .553 efg%. Remember when we thought our backcourt would have the defensive problems? We're turning the Zaza Pachulias into Kevin Garnett.
