I'd prefer someone who can create his own shot.
Although 3 pointers are really great since we have Rondo dishing passes everywhere, having someone who can create his own shot off the bench gives defenses some trouble. Someone who can penetrate instead of just waiting in the wings. Someone who can blow somebody off the dribble. And someone who can shoot. This will make opponents defense play out of their rotation and opens up more people. Rondo can do this but every body else just stands up. If the C's have a double threat like that on the floor, people will be open.
Now, Marshon Brooks is making sense to me.
