Kobe and co are going to have trouble with Rondo if they play.
Two years ago, when the played, Kobe was getting beat on drives while trying to guard rondo off the dribble. Two years later, Rondo has established himself as one of if not the best point guard in the NBA, who has shown he can further elevate his game in the playoffs. His weakness is still his outside shot, but now that he can hit that shot at a decent percentage, and is border line unstopable off the dribble, I expect him to give the Laker's big time issues if they play.
With the way Allen and the Celtics are playing, I think they might win another title.
