Call me crazy, but if recall correctly, he was never that dogged worker like a KG or PP to be in shape, relying on his skill set. I hope that with the injuries, etc. he realizes the benefit to getting in the best shape of his life. He's only 31 for God sakes.
If he comes in shape, with high energy, I believe he can be a defender that will make the offense aware of his shot blocking ability again, and will take up plenty of space the boards. He'll get his offense the same way as Perk, but with more skills and range. Add that with KG's superior interior passing and PP, RA spreading the floor, and Rondo driving and offense will be whatever avails itself in the flow. I'm thinking his mates will dish with a little more confidence that he'll take and make the 8-10 footer that Perk seemed so reluctant to shoot.
The question will be when he moves to coming off the bench and will need to provide more individual post up offense with the second unit, who will not have the same range to keep the middle open (memories of this year's playoffs
). If he can deliver on the block, that would be a BIG option to open some room for the second unit.
Regardless of Perkins return, there will be plenty of need for his stregnth and energy at the end of the grueling season when it's all about keeping Bynum and Gasol away from the basket on offense and then BOX OUT! So, start now...get in shape man!
