The Denner move is one thing--she's joining her twin sister at Notre Dame. I don't have any insights on the other transfer, but that one seems more shady.
Maybe both of these young women were uncomfortable committing to a program that was clearly in flux? Anyone with the slightest bit of knowledge knew that Notre Dame was probably going to change head coaches, even back in April when these young women had to make their decisions. Now that Sparks is the head coach and the assistant coaches are in place, maybe they reconsidered their decisions?
I would say that, with the new transfer rules taking effect, we're going to see a LOT more of this. It's good for the athlete. I'm all for it.
That said, Notre Dame is building both the Women's and Men's distance programs pretty aggressively. It seems clear that they're focusing on distance. Which is great. And, given their head is a distance guy, it's not surprising. They actually have a chance to do well in XC and in individual track distance events. Let's face it, they were never going to compete to team track titles. Good decision (finally!).
Go Irish!
