So, I'd heard some rumblings about this in recent days, but nothing concrete. However, it looks like the cat is out of the bag, and former five-star recruit Shaquelle Evans is leaving the Irish.
Sounds like a playing time situation, though I've also heard rumors of personality differences between the Evans and Brian Kelly. These things are to be expected with a new regime, though the timing is bad for a Notre Dame team trying to replace Golden Tate.
EDIT: TomVH is citing some guy with the same general info (http://twitter.com/tomvh). ND boards are saying he's going to Oregon, though that is very unconfirmed.
EDIT II: Yeah, this is a Bleacher Report article. Consider yourself warned.
