NET? Quadrants? Deciphering lingo about NCAA tourney bids

By Aaron Beard

AP Basketball Writer

If the talk about bubble teams and NCAA Tournament bids was just about the number of wins and losses it would be a simple conversation.

But the Division I Men’s Basketball Committee uses the NET rankings and a four-tiered “quadrant” system to determine who is in or out. And that can be confusing.

The committee issues 36 at-large bids for teams that don’t earn automatic invitations. The process includes using an analytical formula.

Here’s a look at key elements to committee evaluations ahead of the March 15 bracket reveal:

•••

NET

The process starts with the NCAA Evaluation Tool, or NET.

The NCAA moved last season from the RPI to the NET, a more analytical formula incorporating factors such as game results, strength of schedule, game location, scoring margin and net efficiency for both ends of the court.

Yet NET rankings are largely a sorting tool for team resumes, illustrated by last year’s Selection Sunday results.

For example, Houston was No. 4, followed by Kentucky at sixth and North Carolina at seventh. Yet the committee reversed the order when putting each in the Midwest Region, with the Tar Heels as the top seed.

Further down, St. John’s earned an at-large bid at No. 73, along with Arizona State (63), Minnesota (61), Seton Hall (57), Temple (56) and Ohio State (55). Conversely, North Carolina State (33), Clemson (35), Texas (38), Furman (41) and Memphis (46) were left out.

In short, it’s less about where teams stand in the NET compared to where their opponents do. And that’s where quadrants come in.

•••

THE QUADRANT SYSTEM

The NCAA adopted a four-tiered system for 2017-18 to better evaluate game results. It uses the NET to sort games from Quadrant 1 at the top through Quadrant 4, with games away from home carrying more weight.

It’s worth noting: game results can move between quadrants throughout the course of the season depending on the fluctuations of an opponent’s NET ranking.

•••

QUADRANT 1

“Quad 1” wins are the headliners on any resume.

The quadrant includes home games against teams in the top 30 of NET, neutral-site games against the top 50 and road games against the top 75.

For example, Kansas – No. 1 in the AP Top 25 – entered March with an 11-3 record in Quadrant 1. That record included wins on a neutral court against Dayton (third in NET) and at Baylor (fifth) along with losses at home to Baylor, to Duke (sixth) on a neutral court and at Villanova (13th).

Committee chairman Kevin White, Duke’s athletics director, pointed to Quadrant 1’s impact during last month’s reveal of the top 16 seeds so far. Gonzaga got the third No. 1 seed for the West Region ahead of unbeaten San Diego State, earning a potential closer-to-home trip to Los Angeles instead of New York for the East Regional.

“It’s such a fine line,” White said. “I think at the end of the day … it was the fact that the Zags had two really good wins – we thought maybe better wins – over Arizona and Oregon.”

•••

QUADRANT 2

Wins landing here still can help a team’s resume, even if they’re not of the headline-grabbing variety.

Quadrant 2 includes home games against teams ranked Nos. 31-75 in NET, neutral-site games against teams ranked Nos. 51-100 and road games against teams ranked Nos. 76-135.

•••

QUADRANT 3

This is the most likely category for a team to suffer a “bad” loss.

Quadrant 3 includes home games against teams ranked Nos. 76-160 in NET, neutral-site games against teams ranked Nos. 101-200 and road games against teams ranked Nos. 136-240.

For schools in the five power conferences (Atlantic Coast, Big 12, Big Ten, Pac-12 and Southeastern), this is where many games against teams near the bottom of their league standings end up.

•••

QUADRANT 4

Quadrant 4 features the easiest games on the schedule. It includes home games against teams ranked No. 161 or worse in the NET, neutral-site games against No. 201 or worse and road games against No. 241 or worse.

While losses here can wound a resume, they don’t happen often. Last year’s 36 at-large teams went a combined 219-4 in Quadrant 4 as of Selection Sunday. That included St. John’s, Arizona State, Temple and Belmont – the last four teams in – going 39-2, with both losses by the Sun Devils.

•••

STRENGTH OF SCHEDULE

There’s one other noteworthy component: schedule strength, particularly when it comes to what teams control outside of conference play.

Of last year’s 36 at-large bids, only four teams had nonconference strength of schedules ranked 200th or worse (Michigan, St. John’s, Temple and Iowa) as of Selection Sunday. Meanwhile, N.C. State fell on the wrong side of the bubble with no marquee win and a nonconference strength of schedule that was last in Division I (353rd).

NO. 5 SAN DIEGO STATE SHAKES OFF AIR FORCE SCARE, 73-60

LAS VEGAS (AP) — Jordan Schakel’s teammates kept telling him to shoot. San Diego State needed every basket to avoid a major upset.

Schakel scored 14 of his 17 points in the second half as the fifth-ranked Aztecs rallied for a 73-60 win over Air Force in the quarterfinals of the Mountain West Conference tournament on Thursday.

Schakel, who shot 1 of 5 in the first half, hit four 3-pointers in the second half for the top-seeded Aztecs (29-1), who rode a 21-3 run to their 13th consecutive quarterfinal victory.

Yanni Wetzell and Malachi Flynn had 16 points each for San Diego State.

, which is hoping to earn a No. 1 seed in the NCAA Tournament. After surviving the scare from Air Force, SDSU plays the winner of Boise State-UNLV in the semifinals.

Flynn, the Mountain West’s player of the year and defensive player of the year, had three steals, seven rebounds and eight assists to offset a 4-of-10 shooting performance.

AJ Walker scored 18 points for Air Force (12-20), which advanced by beating Fresno State on Wednesday. Walker came off a 24-point game against the Bulldogs.

“It’s Thursday, but it felt like a Saturday championship game the way the two teams played and slugged at each other,” Falcons coach Dave Pilipovich said. “We were good today. We did some really good things.”

Seniors Caleb Morris (12 points) and Sid Tomes (10 points) were the other Falcons in double figures.

“Credit to them,” Tomes said. “That’s why they’re ranked so high in the country.”

Air Force shot 60% in the first half in part to Walker, who scored 14 points in the first half. His 3-pointer with 39.2 seconds left preserved a 37-33 halftime lead for the Falcons.

“I have a very coachable team,” Aztecs coach Brian Dutcher said. “I’ve told them I’m tired of teams shooting over 50% on us in the first half. So they let Air Force shoot 60. They followed my instructions.”

Flynn attributed Air Force’s start to making tough shots.

“A lot of the shots were just good shots on their part,” he said. “We have to give credit where credit is due.”

But the Falcons shot just 27.3% in the second, opening the door for the Aztecs.

Air Force took a 44-39 lead on Morris’ 3-pointer. After a dunk from Wetzell, Schakel then hit back-to-back 3s that gave San Diego State its first lead since early in the first half.

“To be a shooter, you have to have extreme confidence,” Schakel said. “I think everyone on this team has extreme confidence.”

Matt Mitchell hit San Diego State’s fifth 3 of the half for a 60-47 lead with 7:05 remaining, capping off the run.

Air Force went on a 9-2 run to make it 62-56 with 3:46 remaining, but the Aztecs went on a 9-4 stretch capped off by Schakel’s fourth 3 of the half to make it 71-60.

“They had their run, and they played like their season was on the line,” Wetzell said. “We do definitely have to get off to a better start.”

SLOW START

San Diego State went 1 of 6 to begin the game, but responded by making 6 of 7 to take a 19-17 lead on a 3-pointer from Adam Seiko. Flynn was 1 of 3, while Aztecs leading scorer KJ Feagin was 2 of 5 in the first half.

HISTORICAL MISMATCH

San Diego State improved to 33-15 all-time in the Mountain West tournament, while Air Force is 0-17 in quarterfinal games.

COMING UP CLUTCH

Schakel’s five 3-pointers tied a career high set against BYU on Nov. 19, 2019.

DIFFERENCE IN 3S

Air Force was 7 of 13 from 3 in the first half, but went 3 for 11 in the second half. San Diego State shot 6 of 12 from distance in the second half after making 5 of 14 in the first 20 minutes.

“We made some shots early, and when you do that, that basket becomes twice as big and it opens up a lot,” Pilipovich said. “Then you know it’s probably not going to continue that way, but the first half was emotional for us. It just fell into our lap a little bit.”
