Since those guys sit in on the seeding meetings and usually hang around the coaches in their area, if they want "smack talkers" I am sure they can point them in the right direction.
Mooresville Regional: Not necessarily smack talkers but the list of coaches who have had success and have been around for a while with lots of contacts and information you could include would be several:
Darrick Snyder, Maurice Swain, Josh Curry, Alex Johns, Anthony Meister, Brett Nabb.
That regional also has two coaches that influence the area that are not on a high school staff but could add insight to the toughness of the regional:
Chad Red and Sean Schmaltz.
