I generally agree that at some point Gallo needs to become more of a mid-range player, but that cant be the case right now. With as few reliable outside shooters as this team has, a big part of his role at this point has to be keeping the defense stretched to prevent them from collapsing into the paint. Maybe in the future when / if buke gets healthy and makes a return to form there will be someone to keep the defense adequately stretched.
That being said, for all the criticism, which is a bit premature at this point in the season, I think Gallo had a decent game. His shot wasnt falling all that well, but he grabbed some rebounds towards the end of the game. He was open quite a few times towards the end on the outside but Amare had tunnel vision and was making turn overs.
