A couple of weeks ago I computed and posted the average rating per team for several NCAA division I conferences. The team ratings are Jeff Sagarin's computer ratings listed each Tuesday in USA today. I simply total the ratings for the teams in a conference and then divide by the number of teams in that conference. The values computed from the 2/18 ratings (along with the values from two weeks ago, listed in parentheses), are: 1. ACC - 32.4 (31.4) 5. Metro - 53.0 (56.6) 2. Big Ten - 41.6 (40.7) 6. Southeastern - 53.2 (56.7) 3. Big Eight - 46.8 (47.6) 7. Sun Belt - 65.9 (72.1) 4. Big East - 50.9 (48.6) 8. Pacific 10 - 91.9 (89.0) Some comments (intended as observations, not as value judgements): 1. Assuming the computer ratings are reasonable (and I suspect that they are), I still don't know how much the average ratings mean. Because this scheme takes into account all teams in each conference, one or two real dogs at the bottom of a conference can affect the conference's rating significantly. Likewise, great strength at the top could offset weakness at the bottom. 2. The ACC's biggest advantage is at the top of the ratings, where North Carolina, Duke, and Georgia Tech are ranked first, second, and third, respectively. The Big East, on the other hand, enjoys an advantage at the bottom, where Seton Hall is ranked 116th (compared to 143rd for Wake Forest, 164th for Northwestern, and 146th for Colorado). 3. The Big Ten has five teams in the top 17, hence it's advantage over the Big Eight and Big East. Furthermore, eight of the Big Ten's ten teams are in the top 47. (That fact more than offsets Northwestern's 164th place.) 4. The Big East is weak in the middle: there is a relatively large drop from Georgetown (15th) to Pittsburgh (37th) and from Pitts- burgh to Villanova (58th). Whereas the first seven teams in the Big Eight are sprinkled fairly evenly from 4th to 61st, the Big East has four teams clustered between 58th and 80th. After I posted my earlier figures, I received some suggestions that I adjust my procedure by including equal numbers of teams from all conferences, dropping bottom teams, dropping top teams, etc. However, I have once again used ALL teams from each conference, as I was primarily interested in a conference's OVERALL strength. I welcome any additional computations, suggestions, or observations.
