    I've wondered whether I have been too critical of the Committee's giving an at large selection to Rice rather than Minnesota or Cincinnati. Based on the Committee's past patterns, Rice wouldn't have gotten an at large selection, whereas Minnesota and Cincinnati were possibilities for a selection. There's nothing, however, that says the Committee has to follow past patterns, although in most cases it's probably fair to expect them to have at least a reasonable degree of consistency over time.

    So, I went through a different kind of analysis to test the Committee's decisions. This analysis is based on ranking the teams simply as among the three of them, in relation to each of the main factors the Committee considers. For each factor, I've indicated how I rate the three of them. You can do your own rankings.

    ARPI:

    1. Rice #36
    2. Minnesota #48
    3. Cincinnati #52
    ANCRPI:

    1. Cincinnati #51
    2. Minnesota #68
    3. Rice #69
    Note: It might be reasonable to treat Minnesota and Rice as a tie, so 2.5 position for each of them.
    Results Against Top Teams (best results):

    1. Cincinnati T v #5, W v #15
    2. Minnesota W v #11, T neutral v #14
    3. Rice T v #34
    Head to Head Results: None

    Common Opponent Results:

    1. Rice and 2. Cincinnati:

    Houston: Rice W v Houston; Cincinnati L @ Houston

    Memphis: Rice L @ Memphis; Cincinnati T @ Memphis
    Minnesota had no common opponents with Rice or Cincinnati
    Note: I don't particularly like doing common opponent results this way, as it ignores too much information, but it may be how the Committee does it.
    Poor Results:

    1. Rice L neutral v #82
    2. Minnesota L v #136
    3. Cincinnati L v #115, T v #184
    Standing within Conference/Conference Rank

    Regular Season Standing/Conference Rank/Conference Average ARPI
    Note: All three lost in the quarterfinals of their conference tournaments, so that's why I'm using only their regular season standing.​

    1. Minnesota #2.5/4/0.5679
    2. Cincinnati #3/6/0.5491
    3. Rice #1/12/0.5017
    Note: I included the conferences' average ratings for a reason. They show that the differences' in the conferences' strengths are large, in fact vary large especially for Rice.
    When I look at all of these, the main question I ask is how much weight to assign to the different factors. For example, are poor results as important as good results? How important is the ANCRPI? How important are common opponents results, especially when they are as ambiguous as those for Rice and Cincinnati? How important is conference standing and strength? How does the #1 team in the #12 conference compare to the tied for second team in the #4 conference? These all are questions the Committee members have to ask themselves, and the members are not required to assign equal weights to all the factors.

    For me, in the comparisons of these three teams I think the good results are especially important, and more important than the poor results. I think the good results show the level at which a team could compete in the NCAA Tournament: Cincinnati (tie with #5) has shown it has the potential to compete successfully at the quarter-final level; Minnesota (win over #11) has shown it has the potential to compete successfully at the third round level; and Rice (tie with #34) has shown it might have the potential to compete successfully in only the first round. Yes, Cincinnati and Minnesota have some poorer results than Rice, but for the NCAA Tournament, I'm more concerned with not excluding teams that have demonstrated they can be significant factors in the Tournament.

    On the other hand, looking at it in terms of the above comparisons, the Committee's selection of Rice doesn't seem as poor a decision as I previously had thought. But, I still think it was a poor one.

    The NCAA today published its Final RPI rankings for the season, which include the NCAA Tournament games as part of the data base. Unfortunately, there are two errors in the NCAA's data base that make the rankings not right:

    They have the NCAA Tournament game of Northwestern v Butler listed as a Northwestern win, whereas it was a tie with Northwestern advancing on PKs. This error is causing a number of the rankings in the upper end of the rankings to be off.

    Then have the SWAC Tournament game of Alabama State v Grambling listed as a Grambling win, whereas it was a tie with Alabama State advancing on PKs. This error has no effect on the upper end of the rankings.
    The NCAA staff now is aware of these errors and hopefully will correct the data errors and substitute the correct rankings for the ones currently available on-line. In the meantime, here are the correct ratings/rankings for the top 100 teams:

    Just a note that the NCAA has corrected the two data errors I mentioned in the preceding post and revised the final rankings posted on-line accordingly. Kudos to the NCAA staff, they have a very difficult job and do it really well under the circumstances they have to deal with.
