dallas has some real problems, and most of them have little to do with rondo.
dirk has always been a bad defender, but now he is truly awful. he doesn't defend, he doesn't rebound, he doesn't attack the rim.
his shooting is still good enough to make him a useful player, but he has some enormous holes in his game now which don't all show up on the stat sheet.
monta plays little defense, and parsons isn't good, either.
that leaves rondo, who is a mixed bag, and chandler, who used to be elite but is getting old.
add to that a shallow bench and they are going to have some struggles. i agree with some other posters that their offense will be proportionally better in the playoffs considering the shift in style of play that happens. IMO rondo will be OK, though it seems like he might not be able to carry that team the way some might have hoped. the real key will be whether novitzky and chandler have enough in the tank to anchor the offense and D, respectively, at a championship level.
