Think about it, in '85, Max was hurt and Bird had a bad shooting wrist, thus his worst shooting series until '88 in Detroit. That squad had at most, a semi-on/off Wedman and Thirdkill for a bench. Then in '86, both Walton and Sichting arrived, the C's bench was complete and then the legendary season followed. The problem was that neither subs were 25 years of age so it didn't last into the years following.
Now today, similar story, Powe/KG decimated in '09, lost due to a weak bench, much like in '85, after the '84 title with a solid bench rotation. Now, we find a former all star, Wallace, who meshes with KG's passing in-out game, see Walton-Bird combo in terms of ball movement. The difference is that even in '86, neither Ainge nor DJ could stomp the court like Rondo and Ray Ray. But again, DJ, unlike RA, still had a few more seasons of heavy minutes, this could be Ray's last one before his inevitable decline. And like Walton, who knows how many seasons Rasheed can contribute, once he turns 36.
