Sosa's Roland Rating

Here's an explaination of the Roland Ratings from 82games.com. It's a pretty cool way to gauge a player's value when he is on and off the court...

The main components of the 'Roland Ratings' are a production measure (a variant of John Hollinger's PER rating) for a player's own stats versus the counterpart player on the other team while he is on the court, as well as a simple on court/off court plus minus. This rating is actually more of a placeholder until the more sophisticated analysis we produce is made public, but still offers a good fast read on player performance.
