Sixteen may be sweet, but it isn't the only relevant number as the NCAA Division I men's basketball tournament heads into the regional semifinals.
With four games set for Thursday and the other four Friday — the Elite Eight matchups will follow with two each on Friday and Saturday — here are some other numbers worth knowing for each team in this year's Sweet 16.
These statistics will help you learn more about each of the remaining teams and could explain how some of them got this far in March Madness and what started as a 68-team field last week. (No. indicates a team's seed; record is in parentheses.)
EAST REGION
No. 1 UConn (33-3): In the University of Connecticut's second-round victory over Northwestern, Donovan Clingan became just the third player in NCAA tourney history with 14 points, 14 rebounds and eight blocks in a single game. The others to do it were Hakeem Olajuwon for Houston in 1983 and David Robinson for Navy in 1986. Clingan's blocks also were the most by a UConn player in a tourney game.
No. 5 San Diego State (26-10): The Aztecs' Sweet 16 matchup with reigning national champion UConn will mark the fourth time that two teams have faced each other in the tourney a year after meeting in the final. The losing team from the championship game won the rematch in one of the three previous instances, when Duke beat UNLV in a 1991 semifinal. Cincinnati won two straight championship games over Ohio State in 1961-62, while Florida beat UCLA in the 2006 title game and in a 2007 semifinal.
No. 3 Illinois (28-8): The Fighting Illini have won six games in a row, and Terrence Shannon Jr. has scored at least 25 points in each of those. The 6-foot-6 guard has averaged 30.5 points and has shot 52.8% (56-of-106) from the floor during that stretch. He also has shown an uncanny knack for drawing fouls during the streak. Over his past five games, Shannon has taken 58 free throws — and more importantly, he has made all but seven of them.
No. 2 Iowa State (29-7): The Cyclones rank fourth in D-I this season in scoring defense, having allowed just 61.2 points per game. Since falling 73-65 to Houston on Feb. 19, they haven't allowed any of their past 10 opponents to exceed 65 points. Iowa State next faces Illinois, which ranks ninth in points scored per game (84.6) and has averaged 91.3 over its past four.

No. 4 Alabama (23-11): Aaron Estrada and Mark Sears were the first set of Division I teammates since 1996-97 to both have at least 410 points, 125 assists, 120 rebounds, 50 3-point baskets and 40 steals during the regular season. Sears has per-game averages of 21.5 points, 4.2 rebounds, 4.2 assists and 1.7 steals, while Estrada is at 13.3 points, 5.4 rebounds, 4.7 assists and 1.7 steals.
No. 1 North Carolina (29-7): Armando Bacot had seven straight double-doubles and six consecutive games with at least 15 rebounds in tourney play before he ended up with 18 points and seven boards in a second-round victory over Michigan State. His seven straight NCAA double-doubles matched Tim Duncan and Olajuwon for the NCAA record.
No. 2 Arizona (27-8): The Wildcats' first-round triumph over Long Beach State marked the 19th time this season Arizona had five players score in double figures. No other D-I team had that many games this season in which five players had at least 10 points.
No. 6 Clemson (23-11): Each of Clemson's first two tournament opponents has shot below 40% against the Tigers. Clemson won its first-round game by limiting New Mexico to 29.7% shooting, the lowest the Tigers had ever allowed in an NCAA tourney game. Clemson now faces Arizona, which shot 52.8% in its second-round victory over Dayton.

No. 3 Creighton (25-9): Baylor Scheierman is the first player in D-I men's hoops history to have at least 2,000 career points, 1,000 rebounds, 500 assists and 300 3-point baskets. Scheierman, a 6-foot-7, 205-pounder who is in his second season at Creighton after playing three seasons at South Dakota State, has 2,208 points, 1,250 rebounds, 578 assists and 352 3-pointers.
No. 2 Tennessee (26-8): The Volunteers are making their 10th Sweet 16 appearance — including their seventh in an 18-year stretch — but the program has never reached the Final Four and earned its lone regional final berth in 2010.
No. 5 Gonzaga (27-7): Coach Mark Few's program is in the Sweet 16 for the ninth straight time, the longest active streak of any D-I team. Going back to 1975 — the first year that all teams had to win at least one game to reach this round — the record for consecutive Sweet 16 appearances is owned by North Carolina with 13 straight from 1981-93.
No. 1 Purdue (31-4): Zach Edey is the first player since Kareem Abdul-Jabbar (then known as Lew Alcindor) in 1968 to have at least 50 points and 35 rebounds while shooting 65% from the field in his first two games of an NCAA tournament. Edey has shot 67.9% (19-of-28) and has totaled 53 points and 35 rebounds in victories over Grambling and Utah State.

No. 4 Duke (26-8): Jared McCain has gone 10-of-17 from 3-point range through the first two rounds. In the Blue Devils' second-round blowout of 12th-seeded James Madison, McCain became the first freshman to score at least 30 points without committing a turnover in an NCAA tourney game since the event expanded to 64 teams in 1985.
No. 1 Houston (32-4): The Cougars showcased their depth by surviving a second-round matchup with Texas A&M in overtime even after four of their five starters fouled out. They became the first team to win an NCAA tourney game while having at least four players foul out since 1987, when UTEP overcame foul trouble to beat Arizona.
No. 2 Marquette (27-9): The Golden Eagles are 75-29 in coach Shaka Smart's tenure despite posting a negative rebound margin in each of his three seasons. They have been outrebounded in each of their past eight games but have gone 5-3, and they're been outrebounded by an average of three per game this season. The only other Sweet 16 team with a negative rebound margin is North Carolina State (minus-0.8), which faces Marquette on Friday.
No. 11 N.C. State (24-14): Mohamed Diarra has 6.4 points and 7.7 rebounds per game this season, but he has averaged 11.7 and 13.5 over his past six. Michael O'Connell scored in double digits three times and totaled 14 3-point baskets in 31 regular-season games, but he has reached double figures in six of seven postseason games and has gone 12-of-22 from distance during that stretch.
