I really like Tolliver's energy and heart, but it seems to me that the Spurs' greatest weakness is the fact that they are undersized generally and short at least one big body defensively in the paint. Also, they don't get to the FT line much, and they have trouble out-rebounding teams. As much as I like him, Tolliver doesn't address most of these issues, and I just don't think that another potential 3 pt shooting guy is going to really accomplish much-- the Spurs are already the best 3 pt shooting team in the NBA, without him.
