Even if NCHC has three 2 seeds, the 3 seed band is already locked in with SCSU, Notre Dame, UMass, and MTU.
They could just have the lone NCHC 3 seed (SCSU) play QU as long as bracket integrity isn't too far off.
Based on current PWR (if DU ends up being #5 instead of current #4), that'd look like this:
5 DU vs 12 MTU
6 UND vs 11 UMass
7 QU vs 10 SCSU
8 UMD vs 9 ND
