So I was reading an ESPN Insider article on what the Bulls, Thunder, and Heat need to do to get back to their respective conference finals next year. For the Bulls, one of the keys outlined was trying to "dupe" a team into trading for Carlos Boozer. The reason being that according to basketballvalue.com Boozer has posted three seasons in a row where his team was better off with him on the bench based on the +/- data. So I went to basketballvalue.com to see where individual Pacers ranked. I was surprised at the findings. According to the adjusted 1 year ranking, Darren Collison was not only the worst Pacer, he was the worst player in the entire league. He posted a -16.38 for the year. Conversely, Chris Paul was the best, posting an 18.54.
Now I've heard Roy Hibbert was in the same boat as Boozer. The Pacers performed better with him on the bench. This is not the case according to basketballvalue.com. Hibbert posted a 5.85.
So what I'm wondering is, how much does +/- really tell us? Is this a good way to measure a player's value or is it something to just consider when looking at everything?
