I know the chaplain at Vanderbilt personally; he's doing great things. Illinois and Texas A&M have a very good reputation. They even have a "Catholic dorm" (not university housing, obviously) at Illinois so kids can escape the evil and debauchery of a regular dorm.
Even universities like SU have *learning communities* in their dorms that allow for students to avoid a lot of exposure to the typical life of debauchery that most students live.
It's the student's choice, when it gets down to it. The kid raised knowing who he is, what he believes, and WHY he believes it, is far less likely to get sucked in to the hook up, party culture where ever he goes.
Not to mention, that even at SU, there are a large number of Christian and Catholic campus religious groups which are very active and working together. They, along with Fellowship of Christian Athletes, are having quite an impact on the campus. There's a huge outreach going on there now.
Some of SU's latest big name athletes are quite serious about their faith and it's widely known.
