Automatic Qualifier and At-Large Probabilities
AQ (left); At-Large (right). Complete List below.
Last 7 years at-large accuracy: 53 out of 56 or 94%.
Probability of receiving an invitation to the NCAA
Men s Division I Championship Tournament
For an explanation of how the probabilities are calculated see Guide.
The sum of a team s rpi + qw +1/2 sos is a key indicator of the at-large probability.
The Division I Men s Lacrosse Championship is a 17-team, single-elimination tournament. Nine conferences
are eligible for automatic qualification. However, the two lowest-ranked AQ teams, regardless of conference
RPI, will compete in play-in games to determine the final team in the 16-team bracket. The remaining teams are
selected at large. If a team has an AQ bid then its at-large probability goes to 0.00.
Primary Criteria for Selecting At-Large Teams
[1] Strength of Schedule (SOS) Only Top 10 based on RPI*
[2] Results of Rating Pertcentage Index (RPI)
[3] Record against teams ranked 1-5, 6-10, 11-20, and 21+
[4] Average RPI win (average RPI of all wins)
[5] Average RPI loss (average RPI of all losses)
[-] Head-to-head competition
[-] Results against common opponents
[-] Significant wins (defeating teams ranked higher in RPI)
[-] Significant losses (defeated by teams ranked lower in RPI)
[-] Location of the contests
Probabilities are based on current data. As rankings and records change, so do the probabilities.
Note that the SOS on Laxbytes computes all games whereas the SOS appearing here considers only the
10 highest ranked teams. The NCAA has excluded Hampton from the RPI calculation.
