The competition consisted of 77 teams: 40 championship teams and 37 open teams. The divisions were further divided into a men's and women's division: 24 men's and 16 women's teams in the championship division and 19 women's and 18 men's teams in the open division. The divisions were then further divided into groups: eight groups of three teams in the men's championship, four teams of four teams in the women's championship, three groups of four plus two groups of three in the men's open, and four groups of four plus one group of 3 in the women's open with all four divisions engaging in a round-robin tournament that determined teams able to advance to a knockout stage. In all but the three team groups in the men's open division, each team played each other team in their group once while the two three-team groups in the men's open played every team in the opposing three-team group once. Pool play games were two 40-minute halves, separated by a seven-minute halftime and utilized the three points for a win system. After group stage play, the two highest ranked teams from each group in the championship division advanced to their respective knockout stage, with the third placed team in the men's championship advancing to a consolation bracket and the third and fourth placed teams in the women's championship being eliminated. In the open divisions, each pool winner automatically advanced in addition to three additional wild-card teams. Positions 1 and 8 were given to first place teams in groups that didn't have a wild-card team in order of tie-breaking procedures, positions 2, 6, and 7 were given to wild-card teams in order of tie-breaking procedures, and positions 5, 3, and 4 were given to the pool winners from the pools of the 2, 6, and 7 positioned wild-card teams, respectively.
Tie-breaking criteria for group play
The ranking of teams in each group was based on the following criteria in order:
In a tie breaking scenario involving more than 2 teams, the tiebreaker procedure would begin. If one team is identified as different and both remaining teams are still tied, the tie breaker procedure is restarted.
If a tie still remained after the first 5 criteria, the following was used to break a tie:
If there was a three-way tie, a coin-flip would be conducted. The two teams that chose the same outcome would compete in kicks from the mark between each other. The winner would compete with the last remaining team in kicks from the mark
If there's a four-way tie, a drawing of lots would be conducted (only could occur in open division)
Knockout stage games also consisted of two 40-minute halves. The round of 16 and quarterfinals were separated by a seven-minute halftime while the semifinals and finals had a ten-minute halftime. Knockout stage games needed to declare a winner, therefore if a game was tied at the end of regulation, one 15-minute, golden-goal overtime period would begin. If still tied after overtime, kicks from the mark would determine the winner.[6]
Each of the six regions received three automatic bids for the men's championship division and two automatic bids for the women's championship that they awarded to its members. The final bids for each division were considered "at-large", and were given out by NIRSA to teams, typically based on their regional tournament results and RPI.[7]
The remaining teams participated in the open division, chosen on a first-come first-serve basis via online registration beginning on September 12, 2008.[1]
