First Look at Illinois Basketball's Sweet 16 Opponent: Houston Cougars

In this story:
Illinois (26-8) has handled the first weekend of the NCAA Tournament the way good teams are supposed to, cruising past Penn and VCU without much drama. But any hopes of another comfortable evening are about to be thrown directly into the shredder. Waiting in the Sweet 16 is Houston (30-6), one of the toughest, meanest and most battle-tested teams in the country.
Things are feeling SWEET.

As if that weren't enough, the game will essentially be a road contest. Houston will be playing less than five miles from campus, meaning the Cougars will have the crowd, the comfort and just about every possible environmental advantage short of getting to play in their practice gym. If Illinois wants to get back to the Elite Eight, it's going to have to earn it the hard way.
Houston at a glance
The Cougars are led by 12th-year coach Kelvin Sampson, who is about as close to a Hall of Famer as you can get without someone already polishing the plaque. Sampson has dragged Houston all the way back to its Phi Slama Jama glory days, except now the dunks come with a side of full-court defensive misery and offensive rebounding that feels legally questionable. Year after year, his teams look like they were built in a lab to make opponents miserable, and this season is no different. Houston once again looks fully capable of being the last team standing when the dust settles.
Houston has now reached the Sweet 16 or further in seven consecutive tournaments 🐾

And it's not like the Cougars padded their record against the American Conference. They survived the weekly street fight that is the Big 12, finished second in the league and came into the NCAA Tournament looking like a team that enjoys ruining weekends. Since then, Houston has steamrolled Idaho and Texas A&M to punch its ticket to the Sweet 16, continuing its usual routine of defending like maniacs, rebounding everything in sight and generally making basketball look far less fun for the other team.
The Cougars on the court
Key players
Houston has three starters back from last year’s national runner-up, so yes, the Cougars already had plenty of proven talent before adding even more talent. The headliner is freshman guard Kingston Flemings, who looks very much like a future NBA lottery pick and occasionally plays like he is personally offended by the idea of being guarded. The uber-athletic guard is the full package. He is explosive, physical and totally comfortable playing through contact. Flemings is especially dangerous in the midrange, where he can rise up for pull-ups, but he is just as capable of getting all the way to the rim or stepping out and knocking down a three. In other words, good luck.

Flemings is joined by fellow freshman Chris Cenac Jr., another projected first-round pick who has only gotten better as the season has gone on. Cenac is a stretch big who can pull opposing centers away from the basket, and every week he seems to look a little more comfortable and a little more terrifying. Because apparently Houston needed that, too.
Then there is the veteran core. Seniors Emmanuel Sharp and Milos Uzan are back after starting on last year’s title-game team, and both are the kind of guards every coach dreams about. They can really shoot it, rarely look rattled and do all the little things that make Kelvin Sampson smile, which figures to be a difficult achievement.
Junior Joseph “JoJo” Tugler rounds out the group as Houston’s undersized big man at 6-foot-8, but he plays much bigger than that. Tugler is one of the best defenders in the country and an absolute menace on the glass, the kind of player who will fight for every loose-ball opportunity.
Houston may not have quite the same depth as some of the other contenders, but its top five is ridiculous. There are not many teams in the country that can match that combination of NBA talent, experience, shooting, defense and general ability to ruin an evening.
Offense
Houston runs a lot of high ball screens and puts the ball in the hands of its guards, trusting them to get downhill and make plays. That's where the pressure starts. Once the Cougars get moving toward the paint, they are tough to keep in front, and they are willing to take whatever the defense gives them. Unlike a lot of teams today, Houston isn't scared of the midrange. If the rim is crowded and the three-point line is covered, the Cougars are more than happy to rise up from 12 to 15 feet. That makes them difficult to guard because defenses can't just sell out to stop threes and layups.

Around that, Houston spaces the floor with shooters all over the court, which only makes the ball-screen game harder to defend. Help too much, and the Cougars will kick it out. Stay home, and their guards will get into the lane. Then once the shot goes up, it turns into a rugby match. Houston crashes the offensive glass with ridiculous force and consistency, swarming the boards and turning one stop into two or three defensive efforts. The Cougars are absolutely relentless there, and if you don't box out, it's game over.
Defense
This is where Sampson has really built Houston into a monster. Year after year, the Cougars are one of the most terrifying defenses in the country, and this season is no different. They play almost exclusively man-to-man, but it rarely feels simple. Houston has elite one-on-one defenders who sit down, keep the ball in front and make every drive a proving ground. Then once a high ball screen comes, the whole thing starts to look more like a zone. The Cougars love to blitz the ball-handler and have the weakside defender tag the roller, which means the cleanest counter is often a skip pass all the way across the floor over what feels like dozens of arms.

And even when the right read is made, Houston has the athleticism to recover and still contest. That's what makes the defense so nasty. It is disciplined, physical and completely exhausting to deal with. Sampson’s teams always seem to play with the belief that the refs cannot possibly call everything, so they are going to make every cut, drive and rebound as uncomfortable as possible. There are not many things less fun in college basketball than trying to score on Houston for 40 minutes.
Illinois vs. Houston matchup
Keaton Wagler has been about as steady as you could ask a freshman to be. Nothing seems to rattle him, and he has played with the poise of someone far older all season. But this will be the biggest test of his young career. The Cougars are going to bump him, grab him, shove him and generally spend the entire night trying to make him uncomfortable. That is just how Houston plays. Wagler does not have to do everything, but Illinois will need him at his best if it's going to have a real shot in this matchup.
More broadly, this is a game in which the Illini have to stay composed and be ready for a full-on war. Houston wants to turn every possession into a fight, and if you lose your cool, the Cougars have a way of making things spiral quickly. Against Texas A&M, Houston had 10 offensive rebounds, drew a technical foul and a flagrant foul all before the 10-minute mark of the first half. That is not normal. That is Houston dragging a team into the mud and daring it to respond. If Illinois wants to get back to the Elite Eight, it will have to be locked in from the opening tip, match Houston’s physicality and avoid getting thrown off by all the chaos that is sure to come.
