It's incorrect to say we'd definitely be out with a loss to Seton Hall (which some are stating on X), the only thing up for debate is how likely/unlikely our odds would be on Selection Sunday. We still don't know how the rest of the bubble will fare, if Nova/Utah will move up to Q1, etc. Really a crystal ball and Selection Committee input is needed.
Here's one example of why that's the case: Fox Sports has us as a #10 seed today. They have us ahead of UVA, Drake, TCU, Wake Forest, Colorado, Indiana St, & Texas A&M. Does anyone think losing a Q2 game would drop our ranking with them 7+ spots? Even if you account for potential bid thieves or the rest of the bubble doing really well, it's tough to imagine us not being in their bracket on Selection Sunday
Fox is more bullish on the Johnnies than most, but there are also plenty of other brackets that have us as a 10 seed. Too many people just take Lunardi as gospel despite his mediocre record. Fox has been the 75th most accurate bracketologist by the way, ahead of #98 Lunardi. Even if Lunardi is correct there are still (unlikely) scenarios where we could make it if the rest of the bubble does poorly, USF/Richmond don't win, and our resume improves based on Nova, Utah, etc.
Obviously I really want to win on Thursday so this debate can end, but there's no way to say definitively yet whether we'd be in or out with a loss. I also don't think a win vs. Hall 100% locks us in, especially if we get blown out the following day, but it'd make things much more likely of course (I'd guess at least 95%).
