The NCAA Selection committees examine certain criteria which influence
their decisions in the selection process for the NCAA tournaments. These
criteria may include the following: (1) Computer ratings (2) Polls (3) RPI (4) Strength of schedule (5) Quality wins (6) Losses (7) Trend Computer Ratings The NCAA has their own computer rating. Laxpower's computer rating is based on goal margins, strength of opponent and game site (home, away or neutral site). Polls The Coaches Poll is used. RPI RPI is a rating based on Won-Loss-Ties Records of a team, it's opponents and it's opponent's opponents. Strength of Schedule There are numerous ways for determining strength of schedule. Laxpower uses the power ratings of a team's opponents and does a weighted average. We take the average of all opponent's PR and take a power of that sum so that games against stronger opponents counts more than games against weaker opponents. Quality Win Factor The Quality Win Factor is based on the number of wins against quality opponent's. A quality opponent is defined as a team which is ranked in the top 10 by the coaches poll. Every time a team beats a team in the polls, it receives a quality win. If a team is falls from the polls, then the quality win by a team that beat that team disappears. Defeating the number one team is 1.0 quality wins and defeating the 20th team is worth 0.05 quality win points. Loss Factor The Loss Factor is simply the sum of all losses by a team. Trends Games played later in the season count more than games played earlier in the season so the number of losses by a team in its last five games is counted and decreases the chances of a team making the tournament. Formula The TSI is equal to the sum of the following: TSI = – (21 – Poll) + PR ranking + RPI Ranking + SOS Ranking – Quality Wins + Losses + Trend (losses in last 5 games) If the poll contains 25 teams, the first term is then (26 – poll). If the poll contains 10 teams, the first term is then (11 – poll). |
