Msg,

Take a look at the efficiency stats for just guards at NBA.com. They have the stats for the last 4 years available. Last time I looked Marbury was ranked around 50th. I am willing to excuse this year a bit because of his personal problems, but if you look at the trend he has been falling rapidly over the last few years. Granted, stats like these are not perfect, but sometimes they are better than personal opinions when people don't agree because at least there's no emotion involved.
