WCU Alum here.
There are lots of coaches in the WCU/DW tree. The Wofford guy (Bomar) has actually done pretty well there, he got a girl to NCAA's last year outdoors and again in XC this year. He has no facility there, it is really expensive and yet he's doing good (not great) things. Would be a solid hire. Tim Vaught has been at Virginia Tech for a while now, he usually gets the itch right about now to move and he's an alum, he's a great coach and that would be a slam dunk hire.
I get the appeal of Manteo to some, but the guy has zero coaching experience other than being a GA and a volunteer under Danny. Would make a great assistant based on his name, but not prepared to lead a program like WCU where you have to wear many many hats.
The throws coach at ECU isn't leaving. Langley has spent a lot of time at P5 schools and would probably grow frustrated with lack of resources.
The three most prominent coaches out there with ties are Bomar, Vaught and Langley and they were all at WCU about the same time I think. One of those guys would be the best pick.
