NC State athletic director Debbie Yow said she was "disappointed" that the Wolfpack's "total body of work was not rewarded" with a spot in the NCAA tournament despite its lofty rankings in the computer metrics that the selection committee used to evaluate teams.

Of all the teams who missed out on the NCAA tournament field, NC State had the highest NET ranking at 33. The NCAA introduced the NET ranking this season to replace the RPI as a more analytical system that incorporated factors such as game results, strength of schedule, game location, scoring margin and net efficiency at both ends of the court.

Yet NC State -- as well as fellow ACC team Clemson at 35 -- was left out despite having a superior NET ranking than the last four at-large team who will play in the First Four in Dayton, Ohio, on Tuesday and Wednesday. Belmont's NET ranking was 47, Temple's 56, Arizona State's 63 and St. John's 73.

"NC State is ranked No. 33 in the NET, 32 in the KenPom, 26 in the BPI and 24 in the Sagarin," Yow wrote Sunday. "Our Strength of Schedule is 179 and only the Kevin Pauga ranking is higher than No. 33 at 66.

"We finished 8-9 versus quad 1 and 2 programs [in NET rankings], with five of those games outside of our home arena, while playing 14 games against teams in the Top 50 of the NET rankings and having only two losses outside of the Top 22 in the NET. This included a win against the SEC Champions, Auburn University and five games against the field's No. 1 seeds.

"Based on the metrics [cited] above that the NCAA indicated they would use to evaluate team performance, we are disappointed for our athletes, coaches and fans that our total body of work was not rewarded with selection to the NCAA Tournament."

NC State and Clemson were also not even included in the four teams the committee designated as the First Four Out. Those went to UNC Greensboro (NET 60), Alabama (59), TCU (52) and Indiana (54), which were also given the top seeds in the NIT, while NC State and Clemson are 2-seeds.

Selection committee chair Bernard Muir told ESPN that a team's specific NET ranking was not intended to be the determining factor in the committee's choices.

"So the NET is just a sorting tool, it's one tool of many that we have. Also, obviously we're watching a lot of games, and that enters into the discussion as well," Muir said. "We were pleased on how the NET performed, but we're not just going down the list one by one. ... We're truly trying to evaluate full body of work, which is committee-speak, and at the same token make decisions who's the best team that belongs among the 36 at-larges."

However, speaking after the selection show on CBS, Muir said the committee examined how well teams did against opponents in the NET rankings' top quadrant. He noted that a team like Belmont, which went 2-2 against Quadrant 1 teams, was looked upon more favorably than a team like NC State, which went 3-9 against Quadrant 1 opponents, and therefore did not make the most of having more opportunities for Quadrant 1 wins.

Clemson was just 1-10 against Quadrant 1 teams, while Texas, with a NET ranking of 38, went 5-10 and also settled for the NIT. St. John's, despite its much lower NET ranking of 73, went 5-7 against Quadrant 1 teams, the most wins of all the Last Four In and First Four Out teams other than Indiana, who went 6-9 against Quadrant 1. But St. John's also went 5-3 against Quadrant 2, whereas Indiana was just 2-6.

That methodology also might have doomed Alabama, which was just 3-10 against Quadrant 1 opponents, though coach Avery Johnson admitted his team fell short of deserving a spot.

"We don't have anyone else to blame," Johnson said. "We're playing in the NIT because we just weren't good enough during the regular season, and we weren't consistent enough."

The NCAA said UNC Greensboro was in the field of 68 until Oregon won the Pac-12 tournament on Saturday night to earn an automatic bid. But UNCG coach Wes Miller took little solace in knowing how close his Spartans came to being the first Southern Conference team to ever earn an at-large bid.

"It's been an emotional couple of hours," Miller said. "Obviously, we felt like we deserved to be in the tournament. We felt like we were good enough. To find out that you don't get in is heartbreaking, and to find out that you were one spot away, maybe one day that'll be something that makes it feel a little better, but right now it makes it feel a little bit worse."
