aaron brooks is in the lead for most improved player

Sorry guys, but both of you are wrong. PPG by itself is almost useless. If a player averages 40 ppg but shoots 25% from the field and 50% from the ft line, is that impressive?

At the very least, +/- gives you a sense of the overall picture.

PPG isn't useful unless you factor in other statistics. That's why individually, +/- is superior to it.
