Very thorough and well supported analysis. Probably the best one I've ever seen on the Ivy League using analytics and even video to support conclusions.
Big mistake is that Columbia analysis includes Meisner. Wonder if Columbia would still be selected to finish 5th with that correction.
Seems to even have a good handle on incoming freshmen and transfers. Worthwhile read.
Although the analysis doesn't discuss it, the roster presentation shows that Yale, Princeton, Columbia and Penn are the most reliant upon seniors. Other 4 teams much less so.
