Duke. Duke probably won't be a No. 1 seed unless it beats UNC and wins the ACC Tournament as well.
The best thing for us is for Duke to sweep UNC, and for neither team to win the ACC Tournament. Then neither one will be a No. 1 seed, but Duke would get the nod to play in the regional at Charlotte. If we get sent there and UNC is the No. 2 team, the place will be full of Tar Hole fans. They're all over this state. Duke has its fans, but not nearly as many.
