Except ... it’s only been 12 years. Penn won 7 between ‘98-‘99 and ‘06-‘07.
And Penn was only co-champs once in that stretch (‘01-‘02). Harvard has finnished tied for first 4 times in these 9 years. Outright champs only 3 times, and missed the NCAAs in 2 of the 3 where a playoff/tournament was contested (this year pending of course.)
