Purdue basketball is in the Final Four for the first time since 1980 after winning the Midwest Regional. North Carolina State is back for the first time since 1983, when it won the national championship as an underdog.

The Boilermakers (33-4) have had the Final Four on their radar all season, spending time at No. 1 in the nation and remaining in the top 3 throughout. They steamrolled through the first weekend of the NCAA tournament before meeting stern tests from Gonzaga and Tennessee.

Before this unlikely NCAA tournament run, the Wolfpack (26-14) won on five straight days in the ACC tournament out of the No. 10 seed. Without all those wins, they wouldn't have been in March Madness. They were seeded 11th in the South Region.

Here's what you should know for Saturday night's national semifinal. The game is scheduled for 6:09 p.m. ET at State Farm Stadium in Glendale, Arizona. TBS will televise and streaming is on SiriusXM Channel 84.

Purdue's road to the Final Four

Purdue has ridden Zach Edey (30 points, 16.3 rebounds in March Madness, 36-of-54 free throws) and shot 51.7% from the field, 39% on 3-pointers and made 60-of-88 free throws (68.2%) over four games. The Boilers are +19 per game in rebounding, offsetting a lack of opponent turnovers (6.8 per game). Opponents are shooting 40% from the field, 34.1% on 3s and have made 30-of-44 free throws (exactly half of Purdue, at the same percentage, 68.2).

Purdue vs. N.C. State key matchups

Zach Edey vs. D.J. Burns

This is a fascinating meeting of large human beings who have vastly different styles. Purdue's Zach Edey is a classic post player, shooting hooks and dunks the majority of the time. N.C. State's D.J. Burns is a wide body with nimble footwork, quick spins and clever passing to create for himself and teammates.

Trey Kaufman-Renn vs. Mohamed Diarra

Kaufman-Renn helps Edey near the basket but doesn't get the ball much. He will be occupied by Diarra, who has double-doubles in three NCAA Tournament games.

Braden Smith vs. D.J. Horne

These players run the show for their respective teams. Smith averages 12.2 points, 7.5 assists, 5.8 rebounds and 1.5 steals per game. Horne leads the Wolfpack with a 16.8-point scoring average with 40.9% 3-point shooting. Lance Jones may get some time defending Horne.

Scouting report: When Purdue has the ball

First thing is to look for Zach Edey.

The Boilermakers run most of their plays through the 7-4 senior center posting up. If he is single covered, he methodically looks for a hook shot (62.4% field goal accuracy). He draws a lot of fouls (301-of-424, most in the nation, 71%). If Edey draws multiple defenders, he may look to pass to a teammate for a 3-pointer. The Boilermakers are No. 2 in the nation from long range (40.6%).

Purdue also uses a pick-and-roll action with Edey, with the ball handler attacking the basket if defenders stick to Edey. Braden Smith is excellent at finding Edey for alley-oops or teammates along the perimeter out of that action.

N.C. State primarily plays halfcourt man-to-man defense and doesn't force many turnovers, relying on its ability to make opponents uncomfortable (35.3% from the field in the tournament) and grabbing the rebound (+4 per game in the tournament).

Scouting report: When N.C. State has the ball

The D.J.s make the Wolfpack go. D.J. Horne runs the show and can score at all levels and through contact. N.C. State often goes inside to D.J. Burns (13.0 points), who can create his own shot with crafty footwork and is an excellent passer to cutting teammates. Casey Morsell (11.4 points) and Jayden Taylor (11.2 points) are effective complementary scorers, Morsell driving to the basket and Taylor a capable 3-point shooter (36.3%).

Purdue is a man-to-man defensive team that won't force many turnovers. The Boilermakers have Zach Edey near the basket, altering shots and grabbing rebounds.

Purdue basketball roster construction

Old-school. Homegrown. The Boilermakers are among the few teams that largely retained their roster from the previous season. Zach Edey, Mason Gillis and Ethan Morton are in their fourth season at Purdue. Trey Kaufman-Renn and Caleb Furst have been with the program for three years. Braden Smith, Fletcher Loyer and Cam Heide for two. Myles Colvin is a freshman.

Purdue's only transfer is grad student Lance Jones, who came from Southern Illinois.

∎ Jayden Taylor, a junior, came from Butler.

∎ Michael O'Connell, a grad student, came from Stanford.

∎ Casey Morsell, a grad student, has been at N.C. State for three years after one at Virginia.
