By accepting fewer students at UND, there will be fewer UND grads that leave GF or ND.
Seriously though, I like the idea of making it harder to get into UND. In my teaching experience there are definitely some people that don't belong there. However, sometimes it is the people with 4.0's in high schools that struggle the most. I do find it interesting that there is the goal of having more students, and then the goal of making it harder to attend UND. I guess they realized if we had more students, there still wouldn't be anywhere to park.
Edit: Jloos beat me to my last point.
