It is actually simpler than that. Your scenario would give us the outright regular season crown. But if we win out, we hold the tiebreakers over both UVa and UNC. So it wouldn't matter if they split. And we would have a split with FSU, so it would just come down to records against the next best team (in a two-way tie) or pooled head-to-head (in a 3-way tie).
The simplest path is for Duke to win out and for UNC to win all other non-Duke games. That would give us a share of first place, and by virtue of tiebreakers the #1 seed. But that is yucky because we would share the crown with UNC.
Aside from that, we would just need for UNC to be ahead of Louisville, VT, and State for us to take the #1 spot if we win out.
