Just a small question

[alpLewes]

I have been surfing the internet for the answer to this question and finally came here because I couldn't find the answer. I attended the University of Maryland's womens basketball last night against North Carolina and after the game we wondered out loud where the refs came from. Does the ACC have a team that they send or were the refs local NCAA refs? And how does the assigning process work? I am sure with all you experts here someone wil be able to answer...thanks so much.
