Yes, teams in the league make adjustments as Rondo and Dallas are finding out. As Rondo continues to shoot blanks, and teams dare him to shoot the outside shot, his defense will slide too. Unfortunately so will his attitude.
Cuban will not stand for a sulking Rondo, continually trying to shoot himself out of a funk, for very long.
As for the playoff Rondo, you many get a good game out of him here and there, but over all it will be Boston Rondo all over again. Wait until he stops going to the hole because he doesn't want to get fouled, in fear of missing free throws.
