For baseball I enjoy some of the statistical analysis on this site, fangraphs and so on. It goes well with my fantasy sports addiction. I realize that since basketball is largely a team sport. It's also completely totally offseason but still. I was wondering if there was any metrics community for basketball. I go to basketball-reference sometimes, which was what I used to make incredibly incorrect playoff predictions. Any suggestions? Also I'm going to assume that predicting football using math (except maybe turnover differential) is absolute madness but if you can point me to any wizardry about that I'm all for that as well.
