As far as his fitness,I don't know that he is "horribly" out of shape, so much so that he wouldn't help. First, we don't play an uptempo game. We also don't need him to come in and play 30 minutes. He obviously wouldn't have to move a whole lot on offense (because no one else does). Is he out of shape - yes. Is he so out of shape that he couldn't contribute? I don't think so. If he ever gets on the court, I guess we'll find out.
As far as meshing, that usually is an offensive issue. As numerous posters have pointed out ad nauseum, we have NO offensive chemistry. Sidney couldn't do any worse on the offensive end than our strategy of "stand around and jack up contested threes." In fact, he is supposedly a great passer (I think Stans said he would be our best passer) and could be the missing mid-range player who can pass or put the ball on the floor and make a play.
