Start with the one everyone cares about. In the ACC, the combination of last week's results (ND over UNC, Syracuse over UVa) clinched the #1 seed for ND and the #2 seed for Syracuse. Virginia, despite their loss, also clinched a bid courtesy of ND's win over North Carolina.
If Duke beats North Carolina, Duke is the #3 seed and Virginia is the #4 seed regardless of the outcome of the ND-Virginia game. If Duke loses and Virginia wins, Virginia is the #3 seed, North Carolina is the #4 seed and Duke misses the conference tourney. If Virginia loses and North Carolina wins, last two seeds come down to goal differential in the Duke-North Carolina game:
If Duke loses by <5 goals, Duke is the #3 seed and Virginia is the #4 seed.
If Duke loses by 5-6 goals, Virginia is the #3 seed and Duke is the #4 seed.
If Duke loses by 7-10 goals, Virginia is the #3 seed and North Carolina is the #4 seed.
If Duke loses by > 10 goale, North Carolina is the #3 seed and Virginia is the #4 seed.
Other conferences:
America East: One team has clinched a bid in the conference tourney and five teams are in contention for the remaining three bids. Three head-to-head matchups affect these outcomes:
Albany/Binghamton: Albany has clinched a berth in the conference tournament, and earns the #1 seed with a win here. Binghamton needs either a win or a Bryant win to qualify for the tournament.
Bryant/Merrimack: The only matchup where the loser cannot qualify for the conference tournament. Bryant is win and in. Merrimack needs a win and a Binghamton loss to qualify for the tournament. Further, a Bryant win also clinches a tournament berth for Binghamton and eliminates the loser of the UMBC-Vermont matchup. Meanwhile, a Merrimack win clinches a tournament berth for the loser of the UMBC-Vermont matchup.
UMBC/Vermont: Regardless of the outcome, the winner is in, and the loser earns a bid with a Merrimack win over Bryant, but is eliminated with a Bryant win over Merrimack.
ASUN: Six teams earn a bid, four have clinched. Utah, Jacksonville and Air Force all have clinched and currently are in a three way tie for the conference lead. None of them controls their own destiny, however:
Utah: Needs a win and either an Air Force loss or a Jacksonville win. Alternatively, Utah also gets the #1 seed if all three lose.
Jacksonville: Needs a win and a Utah loss.
Air Force: Needs a win and a Jacksonville loss.
Bellarmine has clinched a bid in the conference tournament and is locked into the #4 seed.
Remaining two seeds will be earned by Cleveland State, Robert Morris or Detroit.
Cleveland State: Needs a win over Detroit, or a loss combined with a Robert Morris loss and a Cleveland State loss by < 14 goals.
Robert Morris: Needs a win or a Cleveland State win, or a Cleveland State loss by < 13 goals.
Detroit: Win and in.
