Here's where recent national champions were ranked on January 1

College basketball rankings: Northwestern is legit, plus more Power 36 notes

The New Year is here, and for college basketball fans, that means the NCAA tournament is this year. In order to see which men's basketball teams are in the best position to cut down the nets, NCAA.com analyzed recent national champions to see where they were on Jan. 1 of their respective championship season.

Using kenpom.com's daily rating archives, which date back to the 2011-12 season, and old editions of the AP Top 25 poll, we were able to contextualize where recent national champions stood nationally, when the clocks turned from 11:59 p.m. on Dec. 31 to 12:00 a.m. on Jan. 1. It's also worth noting that kenpom.com, which is a predictive metric, factors its preseason ratings into a team's current rating until Jan. 23, when preseason ratings are phased out. As the season progresses prior to Jan. 23, the preseason ratings have less of an influence as a team plays more games.

Note: Louisville had its 2013 national championship later vacated by the Committee on Infractions.

AP Top 25 poll vs. kenpom.com ranking

It's the age-old question: humans or computers?

In this conversation, the two groups are actually very consistent, on the aggregate, for where eventual national champions stood on Jan. 1. The last eight men's basketball national champions had an average AP poll ranking of 7.3 on Jan. 1, compared to an average kenpom.com ranking of 7.6.

Two of those teams — Louisville in 2013 and Duke in 2015 — had the exact same ranking in both the AP poll and on kenpom.com — No. 4 and No. 2, respectively. Two others (Kentucky in 2012 and North Carolina and 2017) were only off by one spot, and two more had a difference of just two spots in the rankings.

The only two champions among the last eight that had a difference greater than two spots were UConn in 2014, which was ranked No. 17 in the AP poll on Jan. 1 but No. 40 on kenpom.com, and Villanova two years later, when it was No. 16 in the AP poll but No. 2 on kenpom.com.

A major reason why the Wildcats were ranked 14 spots lower in the AP poll compared to its kenpom.com ranking is because Villanova lost to Oklahoma by 23 points, only for the Wildcats to beat the Sooners by 44 (!) in the Final Four, months later.

Six of the last eight national champions were ranked in the top five (actually the top four) of kenpom.com on Jan. 1, and seven out of eight were in the top 10, with UConn being the lone exception in 2014. Through Dec. 30, 2020, the top five teams on kenpom.com were Gonzaga, Baylor, Villanova, Iowa and Wisconsin. Recent history says the national champion will likely come from that group.

Meanwhile, the top five teams in the latest AP poll are Gonzaga, Baylor, Kansas, Villanova and Houston.

Here's the complete breakdown between recent national champions' AP poll and kenpom.com rankings on Jan. 1.

season champion AP Poll rank kenpom.com rank Difference
2018-19 Virginia 4 2 2
2017-18 Villanova 3 1 2
2016-17 North Carolina 9 8 1
2015-16 Villanova 16 2 14
2014-15 Duke 2 2 0
2013-14 UConn 17 40 23
2012-13 Louisville* 4 4 0
2011-12 Kentucky 3 2 1
AVERAGE   7.3 7.6 5.4

*Louisville's championship was later vacated.

How well were national champions playing on offense?

On average, the last eight national champions had an adjusted offensive efficiency rating of 116.5 on Jan. 1, which means that on average, they score 116.5 points for every 100 possessions against an average opponent on a neutral floor. The "adjusted" part of adjusted offensive efficiency factors in the quality of a team's opponents, as well as the location of where games were played.

The average game features roughly 70 possessions, which means that a team with an adjusted offensive efficiency rating of 116.5 would be expected to score an average of 81.5 points in a game against an average opponent on a neutral court.

Through Dec. 30, there are only four teams that have an adjusted offensive efficiency rating greater than 116.5, with two others (LSU and Illinois) that are just below the average. The four schools are Iowa, Gonzaga, Baylor and Villanova, which are all among the top five teams on kenpom.com.

The worst offensive efficiency rating on Jan. 1 for a national champion since 2012 was UConn in 2014, when the Huskies had a rating of 109.9, which would be tied for 40th nationally this season, through Dec. 30.

Here's the complete breakdown of the last eight national champions' offensive efficiency on New Year's Day, listed in descending order by adjusted offensive efficiency rating on Jan. 1 of their respective national championship seasons. Also listed is each team's efficiency ranking nationally on Jan. 1.

champion season adj. Offensive Efficiency Rank
Villanova 2017-18 124.4 2
Duke 2014-15 120.3 1
Villanova 2015-16 118.0 8
North Carolina 2016-17 116.8 9
Virginia 2018-19 116.4 8
Kentucky 2011-12 114.9 8
Louisville 2012-13 111.7 21
UConn 2013-14 109.9 53
AVERAGE   116.5 13.8

What about defense?

As the table above shows, the last eight national champions had an adjusted offensive efficiency rating that ranked, on average, just better than 14th nationally on Jan. 1, which is very similar to the average of their adjusted defensive efficiency ratings on Jan. 1.

Their defenses had an average adjusted efficiency rating of 89.9 and an average national ranking of 13.5 on Jan. 1. Through Dec. 30, there are 13 schools with an adjusted defensive efficiency rating better than that average — Texas Tech, Tennessee, Clemson, Texas, Ole Miss, Kansas, Wisconsin, Stanford, Baylor, Virginia, Memphis, Houston and West Virginia. Of those schools, only Baylor also has an adjusted offensive efficiency rating that's better than the average of the last eight national champions on Jan. 1.

Here's a breakdown of the defensive prowess of the last eight title-winners when the calendar turned.

champion season adj. defensive efficiency rank
Louisville 2012-13 83.8 1
Kentucky 2011-12 85.4 2
Virginia 2018-19 87.7 5
Duke 2014-15 90.2 16
North Carolina 2016-17 90.9 10
Villanova 2015-16 91.8 10
Villanova 2017-18 94.5 25
UConn 2013-14 95.4 39
AVERAGE   89.9 13.5

There are still two months between now and the start of March, so teams have rooms to make adjustments, tinker with their starting lineups and rotations, and improve, but recent history says that one of the teams that's currently near the top of the AP poll and efficiency rankings will likely be the one that wins the NCAA tournament.
