Sorry, but I think that's a bit too much. There was a whole discussion on the topic of "flagship" earlier, and I think we should steer clear of the word since a consensus cannot be reached regarding it. However, I made one change in the intro to differentiate BYU from its "sister schools", saying it is the "the oldest existing institution in its (LDS Church's) [Church Educational System]]." This is a fact and elaborates on the CES template at the bottom of the article. Hope this helps.
