I believe the chart indicates all games played.That’s good pretty good if it’s just conference games. If it’s all games then maybe not so much as it could be indicative of cupcake schedules.
Also, if it is just conference games you have to remember for a long long time there were only ten teams in the conference. That takes some of the bluster away from sixth place. Also for a while there were even less teams than ten in the conference.
