Yeah, the badly outscored notion is completely overplayed. Rondo's problems has always been consistency in keeping opposing PGs off the paint, not necessarily because they scored, but because it forced our big guys to step up and leave their defensive assignments open.
The other problem with Rondo's consistency is his tendency to run the offense ineffectively in the 4th quarter, particularly when we have the lead... walking the ball up the floor, milking the clock, often leaving us shooting bad shots at the last second, or playmaking too much in a way that keeps us strictly as a jump shooting team.
He improved on both of these areas during last year's playoffs, but it's always been my biggest knock on Rondo's play, and it still creeps up too often for my comfort.
Then you have time after time huge advantages from Rondo against his opposing PG, and yet he fails to capitulate. I think Rondo is the only elite PG who can't consistently destroy Derek Fisher for example.
