Define "historically"

Until about 15 or so years ago, the top Indiana talent went to UT, and those who didn't usually ended up at Purdue. As Purdue, declined, it became the top talent going to UT, then ND, and finally with UT's decline, ND now has Indiana well in hand.

Don't get me wrong. ND used to get very good Indiana talent (Riley was underrated as a recruit). Most were in the top 25-30 (but not top 10) range. In fact, about 20 or so years ago ND actually had historically had (up to that point) more players from Michigan than from Indiana.
