Derrick Rose tore his ACL Saturday afternoon in Game 1 of the 2012 NBA playoffs versus the Philadelphia 76ers. The key question is: can the Bulls find production elsewhere to replace him in these playoffs and the first part of the 2012-13 season? Chicago went 18-9 in games without Rose this season. C.J. Watson was the primary backup, averaging nearly 10 points and four assists with a near league average PER (player efficiency rating) of 13.
