In about a week we are going to start grouping teams as "locks", "need to win BTT", and "bubble".
As a reminder heading into that, I use those terms literally, ie:
"Lock": A lock, to me, is a team that could lose every remaining regular season game, get the worst possible BTT match-up and lose that, and would still make the tournament.
"Need to win BTT": A team that needs to win the BTT, to me, is a team that could win every remaining regular season game, get the best possible match-ups in the BTT and win all of their BTT games except the CG and still would not make the tournament.
"Bubble": Bubble teams, to me, are all the other teams.
Thus, I don't think any team in the B1G is a lock and I don't think any of them are in need to win BTT territory yet.
Michigan (10-2/21-2) has the best record but I don't consider them a lock because if they lost out they would head to the BTT at 10-10/21-10 and if they then lost their BTT opener they would finish 10-11/21-11 along with being the losers of nine straight and 10 of their last 11. They *MIGHT* make the tournament anyway but it wouldn't be a given because that horrible finish just might keep them out.
Conversely, Penn State (1-11/8-15) has the worst record but I don't consider them to need to win the BTT because if they won out until the BTTCG they would finish 12-12/19-16 and that fantastic finish just might get them in.
At this point, IMHO, M(10-2/21-2), PU (9-2/16-6), MSU (9-3/18-5), UW (9-3/17-6), and UMD (9-4/18-6) are all on the cusp of becoming locks. Similarly, PSU (1-11/8-15) and UNL (3-9/13-10) are on the cusp of "need to win BTT" status.
