Rondo doesn't need to adapt.
He just plays his game like always. It's the other guys that haven't been playing up to par until now.
Yes, this is the point that people are seeing. Rondo's detractors are smugly claiming that the Celts, with their increase effort and improved ball movement, have been able to maintain our spot in the mid-20s on offense. The bigger picture is that when the other players move around (and hit their shots) when Rondo's playing and running the offense we're a top 10 offensive team.
Imagine if KG had been injured early last year when we were 20th or so on defense. It's possible that, with the team rounding into shape and Bradley and Steamer playing more that we could have still been a bottom 10 defense without KG. I wonder how many claims there would have been that they had proof that we don't need KG on defense anymore.
