this is what happens when you rush players back from injury. They were put in a tough positions because of injuries, but Perk originally wasn't supposed to come back until march . You can easily hurt something else if you are trying to take any stress off one leg and put it on the other.
This plus the rushing back of delonte really has me scratching my head about the C's medical staff.
Add in the JO signing and the medical staff looks like they are doing a horrible job.
