IMO it will be 1 Parco, 2 Lovett, 3 Shayne.
B10 Tournament doesn't seed on bonus points or care about home/away. Look at their overall records -- Parco will have the best overall W-L record (18-1), vs Lovett (15-2) and Shayne (17-1).
Also, Parco will have more ranked wins (not counting each other):
- Parco: #5 McNeil (UNC), #8 D'Emilio (anOSU), #9 Abas (Stanford), #13 Webster (Illin'), #17 Young (OKST), #25 Cartella (NW), #29 Roberts (Goofers)
- Lovett: #5 McNeil, #10 Alvarez (Rider), #14 Realbuto (UNI), #24 Gilcher (scUM), #29 Roberts.
- Van Ness: #8 D'Emilio, #12 Williams (Little Rock), #13 Webster, #24 Gilcher.
Lovett will then get the 2, based upon H2H vs Shayne.
If Parco loses before B10s, then 1 Lovett, 2 Van Ness, 3 Parco, because then it's no longer a 3-way H2H for the 1. But Young is Parco's toughest remaining opponent.
Ultimately, these 3 guys are likely the 2-3-4 seeds at nationals, based upon their B10 Tournament finishes, behind 1 Henson. Worst case for any of them is getting the 5.
