Narduzzi has coached with Canada in the past. Canada has a coaching history with NC State's current head coach. I do not know which connection is stronger. He might like his situation at NC ST. I almost included Canada on my list but wanted to limit it to ten.
Of candidates with no connection to Narduzzi, I think you are on the mark with Coley and Mangus. An unlikely choice, but someone who I think would do great is Brain Angelichio.
The thing I like about Canada is he will really make the guys go the full 110 yards every day in practice.
Are there ANY inside candidates that would be good with this kinda promotion?
