Skipper ratings over their careers
Week at Jones College PrepWeek before / elsewhereLine colour = skipper (’yy = graduating class)

Weekly rating of every skipper on the roster across their whole career so far, one point per week their rating moved. By class year lines every graduating class up at the start of its freshman year, so each class sits one year further left than the one after it. Hover a line to isolate it.
