Ray Allen can create his own shot; he's just not asked to / allowed to in our offense, for the most part. You don't score 26 points per game by being a spot-up shooter.
I agree whole-heartedly with wdleehi's assessment. I put a lot of the blame on Paul's shoulders; he is the best player on our team at penetrating and getting to the line, and for the most part, he hasn't been doing it. As mentioned above, he's settling. The same is true of Rondo, by and large.
