Keep in mind the day we lost Sully we acquired Thomas (and Jerebko for that matter) I think people are attributing the improved play to them, and rightfully so. They have been an infusion of energy, scoring and athleticism we have long lacked.
Also keep in mind the one game w/out Sully and prior to Isaiah we lost to the Kings in a game where our frontcourt got dominated. Sully tends to be a beast against the Kings. We missed him that game and I think we still do. Most fans understand that.
