Comparing NE Cairo and Salisbury - a Statistical analysis 3/27/2022

 Justin @Ima_little_loud was questioning the placement of Salisbury and NE Cairo in my earlier blog on the Missouri Basketball Coaches Association poll and my ratings of each class.  Justin claim was that Salisbury beat NE Cairo by 32 earlier in the season and NE Cairo lost their first district game to Van Far by 3 and should not even be ranked.  NE Cairo did beat Salisbury by two in a rematch.

I went back through both schedules and here is my re-analysis of both teams.

NE Cairo had a weighted 118 rating in my final class two poll (rounded up to 118).  Reviewing their schedule below, their opponents rated at 95.  They finished 21-6 although their points for/points against would suggest a higher winning percentage.  Using the Pts For/Pts Against Pythagrean formula, their winning percentage predicted at 99.6% but the large point differential may be an outcome of a weak schedule.  

Their consistency score (+/- 16.5) was fairly large for a elite team.  The higher the consistency score, the less predictable the team will be in winning games where they are more highly rated.

Upon re-calculating their raw rating, I ended up with a 120.4 rating.



Salisbury had a 117 weighted rating in my final class two poll (rounded up from 116.6).  Reviewing their schedule, they actually played a stronger schedule than NE Cairo AND had a better record at 23-3.

Salisbury's points for/points against suggested that by the Pythagrean win % formula that they should win 98% of their games and they did win 89% AND their consistency score was +/-11.4 points, suggesting that Salisbury played much more consistently during the season than NE Cairo.

Even with those positives (winning record, consistency, strength of schedule), the raw rating for Salsibury was 119.1 compared to NE Cairo's 120.4.  

Given the re-analysis of these two teams, I would potentially move both teams up in the class two ratings, but NE Cairo would still be one rating point better than Salisbury.


If I did change their ratings, I would have to go back and check every top 20 team that raised a fuss.  The new ratings might look like this:


But I am not going to re-issue my rankings.  Under further review, NE Cairo is still a hair better than Salisbury, even if they didn't win a district game.

Gramps Braggin' Rights Missouri Boy's Class Four Basketball Ratings by District - 2/10/2021

 Gramps Braggin' Rights Missouri Boy's Class Four Basketball Ratings by District - 2/10/2021 As I stated earlier, I am not fully caught up on all teams in all classes but with district seeding meetings (some have already occurred) and tournaments right around the corner, I am posting what I have.  Here are the Class Four boys ratings by district and my comments about each district: District 1: Take New Madrid County Central over Cape Notre Dame and run. District 2:  Jobe Bryant and the Park Hill Central Rebels dominate. District 3:  St. James edges Owensville District 4: Confluence Academy spoils another Cinderella run by Lift for Life. District 5: How do you spell Domination...?  V-A-S-H-O-N District 6: MICDS and Whitfield could play three OTs to decide this.  I can't, you can flip your own coin.  Brandon Mitchell-Day might be the difference-maker here. District 7: St. Charles West, Orchard Farm, and Lutheran St. Charles battle for the title.  I ...

West County Leadwood and Steelville - an analysis of schedules and explanation of comparative statistics

Image
Sometimes I think I need thicker skin.  When you get into a rating of teams, the old saying from Lincoln "you can satisfy some of the people all of the time, but you cannot satisfy all of the people all of the time" or something like that.  No matter how hard I try to keep the ratings equitable, there will be a complaint, an inquiry, or a question about their team's placement. I had an inquiry this morning about class three Steelville and West County Leadwood.  The inquirer indicated that West County had made the final four and had beaten Steelville in a February game by 47-37.  I don't always respond to such questions with this much analysis but it does two things: 1) it validates my ratings and 2) it helps explain to everyone how I get to where the ratings end up. I told the inquirer that I would take a look but she said it did not matter because head-to-head should trump everything else.  I don't agree with that unless it is a state championship game (besides...

Upsets, Upsets, Upsets and some bad calls 3/06/2022

 Wow!  It must be March and the madness has already begun with upset, after upset, after upset.  Teams that ranked high in Gramps Braggin Rights ratings are dropping off the board left and right.  It makes you wonder if the MSHSAA play-off system needs to be revised so that the best basketball is not played in the District semi-final or final game but rather in the final four? There were some very controversial games too.  I do not have the details, but KC Center lost to Pembroke Hill because of a technical call because a fan ran over the Pembroke Hill bench after Center scored an apparent winning basket with 1.4 seconds left.  One of the Pembroke players actually tried to grab the driving Center player but there was no call.  When I first looked at the video, I thought the official was calling an intentional foul on the Pembroke player which would have waived off the basket, and given Center two free throws and the ball. And that ref did call a techni...
