I have made reference to this several times in comments, but I finally have a link to back up what I’ve heard from multiple sources:
NB: How many years are you planning on staying in college?
BC: This is my fourth year, so it’s probably my last year.
NB: Aren’t you a redshirt junior?
BC: Yeah, I am, but I’m graduating early, so I don’t really want to stay too far back.
NB: You don’t plan on doing a grad school year and playing your senior season [of eligibility]?
I don’t know anything about this particular website, but it’s 100% consistent with what we have heard all year. So, when you project the Wolfpack roster for next season, assume we will need to replace all of Costner’s offensive contributions (in addition to that of Fells and McCauley). That will be a significant challenge for the 2009-10 Wolfpack.
