His "major contributors, significant contributors, role players, limited roles" categories are going to either need a larger sample to be accurate or some fine-tuning. Yeah, I was hoping there'd be an explanation on the main page explaining those, but there was none. He doesn't really measure individual defense, so those rankings seem to be offensive based only with in the very least a large slant towards scoring. The titles are more just fun to see so you can make fun of Chris Kramer being ranked "nearly invisible" After looking around a little bit, they seem to basically be completely based on usage rate. The problem is they don't put any weight on % of minutes or any other factors. Thus Matt Gatens is a role player (2nd most minutes, highest offensive rating) and Fuller who was practically out of the rotation and has only played 37% of the minutes is a major contributor. So basically if you had a guy that gets 7 minutes a game but chucks up a bunch of shots in those minutes and has a lot of turnovers, he would ranked "major contributor".
