(Note: tables are always tough here, so I only put the Big East at the end of the explanation and left the table of the other 21 conferences and all 351 teams on the Cracked Sidewalks version)
While the Big East seeks a second National Title in three years, the conference had a slightly disappointing tournament with some near misses - finishing almost even with the Big Ten but behind the ACC, SEC and Big 12 in overall play.
After the season I match each conferences #1 team against the #1 team in the other 31 conferences, then the #2 team against the other #2s etc. to get a composite record for each conference from top to bottom. The "winner" is determined as the team that had the better tournament with teams getting a credit for 1.0 for each line in March Madness, 0.4 for each NIT line (yes, NIT Champ Penn State gets more credit than a team that won one NCAA game), and less for each CBI or CIT line.
Obviously, a team like Maryland that did not go to a tournament is better than CBI and CIT teams, which only invite Mid-Majors, but this really doesn't matter in scoring because as the 7th place team in the Big Ten they "win" all their match-ups with smaller conferences 7th best teams. If teams are tied in their tournament success or neither on went to a tournament, then the team's www.kenpom.com ratings determine the "winner."
Marquette gets 1.2 credit for being on three NIT lines, which puts them slightly ahead of Providence and Creighton with a 1.0 for making the NCAA tournament but not winning a game. That gives Marquette the 5th best tournament success in the Big East, and when matched up against the 5th most successful teams from the other conferences they go 28-3 with losses only to UNC of the ACC, Ohio State of the Big Ten and Auburn of the SEC.
That is part of a composite 267-33 projected "record" for a .890 winning percentage that ranks behind only the ACC (327-10, .970), Big 12 (282-18, .940), SEC (314-23, .932) and just behind the Big Ten (301-36, .893). Here is the breakdown and tournament history for every team by conference.
