There are two exciting parts of championship week. Obviously, there are all the championship games. But then there is watching the desparation of the bubble teams trying to make one last good impression on the Selection Committee.
We might not be able to know for certain, but there are some historical rules that can help us really identify the teams who are playing for seeding vs. the teams who are playing for their tournament lives.
In this first piece, we will break down the conferences. This year, due to the Ivy League cancelling their winter sports, there are 31 conference champions and 37 at-large bids. In order to help start identifying the bubble, it can help to understand the potential teams.
At the end of the day, when the NCAA used the RPI, the worst RPI to ever get an at-large bid was in 1999 when New Mexico made it as #74. In 2019, the first time the committee used the NET, they came close to breaking this record – as #73 St. John’s made it into the field as the last at-large team. We can be a little ultra conservative and probably make a safe assumption that you will not be an at-large team if you are not in the top 80 of the NET rankings.
13 of the conferences do not have a team in the top 80 – these are definitely one-bid conferences. Those are (added their conference tournament winner if it has happened): America East, Atlantic Sun (Liberty), Big Sky, Colonial, MAAC, MEAC, NEC, OVC (Morehead St), Southland, Summit, Sun Belt (Appalachian St), SWAC, and WAC.
Another 6 conferences have 1-2 teams in the top 80 NET rankings. But they likely will be a one-bid conference. The reason for this is the best of those teams is ranked 54th (UC Santa Barbara from the Big West). 54th is really good, but all these teams have a large hole in their resume – quad 1 victories. Of these 8 teams, only #74 Louisiana Tech has a quad 1 win – and their lone win is a road win against #73 North Texas.
So, the Big West, Big South (Winthrop), MAC, Horizon, Conference USA and Southern conferences join the one-bids.
I suspect there is one more one-bid conference, but they would create a record depending on how far a loss causes the team to fall. The best ranked team to not get invited to the tournament (based on RPI) was #21 Missouri State in 2006. Currently, Colgate sits at 8th in the NET. I can’t imagine the Patriot second-place team can get an at-large bid based on having beaten only 4-5 teams in the Patriot league. But their NET ranking will put them on the bubble if they lose – probably the wrong side, but still…….
The Missouri Valley is decided – Loyola Illinois defended their regular season championship and do not need to worry about Selection Sunday (although with their NET ranking of 10 and being ranked in the polls, they were likely safe anyways). Drake is 25-4 with a ranking at 47 – they will probably be one of the Selection Committee’s most difficult decision.
So, that then leaves us with 10 conferences with a chance at multiple bids (outside the case of if Drake gives the MVC a second team). Here they are with the number of top 80 teams they have:
Big 10 (12), SEC (10), ACC (10), Big 12 (7), Big East (7), Pac 12 (6), Atlantic 10 (6), American (4), Mountain West (4), WCC (3).
So, they represent 69 teams – 10 of them likely will get their bid from the conference championship. Adding Drake gives us 60 teams fighting for 37 spots (OK – I guess ultra-conservatively 61 if we need to add Colgate if they lose on Wednesday or Sunday – they would be better off not joining the at-large discussion).
This establishes a few things. First, we likely have 19-20 one-bid conferences where they will be sending their conference champion to the dance.
Next, there are 9 conferences that can cause the bubble to shrink. The Atlantic 10 championship is St. Bonaventure vs VCU – both top 80 teams. If BYU can beat Pepperdine tonight, it will drop to 8 – since Gonzaga is beating St. Mary’s by 27 pts in the second half, BYU is in the top 20, and if St. Mary’s miraculously comes back, they are also in the top 80.
The major 6 conferences normally aren’t responsible for the bid-stealer. With typically over half of your conference being top 80 teams, the chance that one of the worst teams in the conference can go win games on 4-5 straight days is unlikely. So, if you are rooting for a bubble buster, you will be watching the American and Mountain West conference tournaments – and rooting for chaos.
