NCAA FOOTBALL 2015: Week EIGHT Review According to SBPI [SportsBoss Power Index]

Here is the fourth CFB SBPI installment of the 2015 season.  To read more about how I calculate my ratings look back at last week's entry that also has links to other entries surrounding this topic.

Without further ado here are the Top 25 rankings through action on Saturday October 24.  The columns OFF/DEF/TOTAL represent where each team statistically ranks across 128 teams in the FBS; we also include the AP Poll, USA Today Poll, ESPN’s FPI & Sagarin’s rankings which can all be used as a solid comparison tool followed by each team’s SOS adjusted RATING and RANK:

Here are additional teams of note that did not make the SBPI Top 25 but were ranked inside the Top 25 of at least one of the other four sources I use for comparative purposes:
#28 Mississippi State (#25 AP, #20 FPI, #20 SAG)
#29 Michigan State (#6 AP, #5 USAT, #22 FPI, #18 SAG)
#30 Houston (#18 AP, #19 USAT)
#31 Duke (#22 AP, #18 USAT)
#32 Memphis (#16 AP, #16 USAT)
#33 Baylor (#2 AP, #2 USAT, #1 FPI, #3 SAG)
#35 North Carolina (#24 FPI, #25 SAG)
#36 UCLA (#24 AP, #25 USAT, #18 FPI, #23 SAG)
#41 Temple (#21 AP, #22 USAT)
#44 Texas A&M (#16 FPI, #24 SAG)
#50 Toledo (#20 AP, #20 USAT)

Let’s take a look at the relationship between SBPI & record in matrix form (currently there is a 78% correlation between SBPI ranking & wins, UP from 77% last week):

Of the Top 25 SBPI teams 6 are undefeated, 14 have at worst one loss & just 2 are under .500 – Arkansas & Tennessee, who have played the 4th & 2nd toughest schedules in the country, respectively, which boosts their rating.  Of the SBPI Top 50 almost half (23) of the group has a one or zero losses.  The SBPI, and looking at it in this sort of breakdown, can add value by seeing which teams have suffered perhaps from “bad luck” so far [playing better football than their record indicates], or teams that may have been “lucky” this year [rating lower on the SBPI scale than their record suggests]. 

Here are the five lowest rated SBPI teams that have a winning record:
#98 Rice 4-3 (faced 113th toughest schedule)
#91 Georgia Southern (faced 110th toughest schedule)
#90 Marshall (faced the worst schedule [128th] in the country to date)
#84 Kentucky (faced the 35th toughest schedule)
#83 Auburn (faced the 21st toughest schedule)
