Offense had stood out all season for Illinois, only for the defense to step up in March Madness<\/a>.<\/p>\n

Arizona and Michigan have been part of college basketball’s top tier all year with elite play at both ends of the court, and they’ve been even sharper at the offensive end in the NCAA Tournament.<\/p>\n

Now that trio joins UConn for this week’s Final Four<\/a> in Indianapolis. The Huskies and Illini meet in Saturday\u2019s first semifinal, followed by the Wolverines and Wildcats.<\/p>\n

All four teams rank in the overall top 10 of data-driven college basketball rankings for KenPom<\/a>, Evan Miyakawa<\/a> and Bart Torvik<\/a> going into the Final Four. That includes the Wolverines and Wildcats ranking 1-2 for all three currently, as well as posting some of KenPom’s best net-efficiency rankings ever recorded.<\/p>\n

Illini’s defense<\/p>\n

Illinois (28-8) entered the NCAA tourney ranked second in KenPom’s adjusted offensive efficiency by averaging 131.2 points per 100 possessions while ranking just 28th in defense (99.1). Yet the South Region champion’s defense has allowed .976 points per possession in the NCAA Tournament to lead the remaining four teams.<\/p>\n

\u201cWe\u2019ve been very good throughout the season at times,\u201d coach Brad Underwood said before the regional final win against Iowa<\/a>. \u201cWe just haven\u2019t been that consistent.\u201d<\/p>\n

Illinois allowed Penn<\/a>, VCU<\/a>, Houston<\/a> and Iowa to score on just 41.2% of their possessions. The Illini also dominated the glass<\/a> (plus-16.3 per game) to grab the rebounds that completed those defensive stops.<\/p>\n

They’ve done it all with the nation’s tallest roster, with seven players from Saturday’s eight-man rotation standing 6-foot-6 or taller. That has included an influx of European talent<\/a>, including Croatian twins Tomislav (7-1) and Zvonimir Ivisic (7-2), as well as 6-9 forward David Mirkovic from Montenegro. The outlier among that big lineup, 6-2 senior guard Kylan Boswell, is a strong backcourt defender.<\/p>\n

UConn (33-5), meanwhile, has scored on 52.2% of its possessions going back to the second-round win against UCLA, with a high of 54% in Sunday’s comeback from 19 down to shock top overall tournament seed Duke<\/a>.<\/p>\n

Terrence Oglesby, an analyst with ESPN and Field of 68, pointed to the Illini’s ability to play in the gaps to disrupt offenses trying to move the ball and space the floor to create mismatches or lanes.<\/p>\n

\u201cPositionally, they’re just elite on top of being massive,\u201d said Oglesby, a former Clemson player. \u201cYou go to the Balkans to grab all these guys, and they’re huge and they’ve also been well coached coming all the way up. … The good part about being pretty gap-heavy is the fact that if you’re huge, you can still get out to shooters.”<\/p>\n

Offensive flow<\/p>\n

Michigan (35-3) has the most efficient offense of the Final Four teams, averaging 1.361 points per possession in tournament wins over Howard<\/a>, Saint Louis<\/a>, Alabama<\/a> and Tennessee<\/a> to edge Arizona’s similar average (1.341).<\/p>\n

The Midwest Region champion became the first team to score 90 points in every game through to the Elite Eight since UConn did it in 1995 before falling 102-96 to eventual champion UCLA. Dusty May’s Wolverines are shooting 55.9% through four games, including 44.6% (45 of 101) from 3-point range, and have scored on 60.4% of their tournament possessions.<\/p>\n

Before the Sweet 16 win against Alabama, guard Roddy Gayle Jr. said May’s system allows the Wolverines to play \u201csuper free.\u201d<\/p>\n

\u201cHe does a lot of free-flow offense,\u201d star Yaxel Lendeborg said. \u201cHe has certain sets, but the sets aren\u2019t necessarily for shots. It\u2019s just for movement, just to get the defense out of their shell, and then attack off those mistakes.”<\/p>\n

Net efficiency<\/p>\n

The Wolverines’ semifinal against fellow 1-seed Arizona (36-2) will pair teams with all-time great KenPom efficiency metrics.<\/p>\n

KenPom bases efficiency on points scored or allowed over a standardized 100-possession pace to eliminate tempo as a factor. Overall rankings are determined by net efficiency in terms of how much a team\u2019s offensive data outpaces its defensive numbers.<\/p>\n

Michigan currently leads the country at plus-39.02 after the regionals, followed by Arizona at plus-38.76. By comparison, only two teams have finished a season with higher KenPom numbers going back to the 1996-97 season: Duke in 1998-99 (plus-43.01) and Duke last year (plus-39.29).<\/p>\n

\u201cThese are these massive teams that also have enough shooting. but they\u2019ve leaned into the everything else,” Oglesby said. “They’ve leaned into the controllable aspects: rebounding, being big, being physical. … I wouldn\u2019t say that the championship game is Michigan and Arizona, but those two teams have just been a freight train going through.\u201d<\/p>\n

Neither of those high-efficiency Duke teams managed to cut down the nets. The first lost to UConn in the title game<\/a> and the second fell a year ago to Houston<\/a> in a late collapse in the national semifinals.<\/p>\n

What’s ahead<\/p>\n

The season’s final three games will pair strength-on-strength in the halfcourt.<\/p>\n

The four teams have played man defense on 97.3% of their combined halfcourt possessions, according to Synergy. Arizona, Michigan and UConn all rated as \u201cexcellent\u201d in the 91st percentile or better, while Illinois is rated \u201cvery good\u201d in the 81st percentile.<\/p>\n

Yet Synergy rates all of those teams as \u201cexcellent\u201d in running halfcourt offense against man defense, with Illinois (97th percentile) and Michigan (96th) as the best.<\/p>\n

The key for Saturday could be which teams can get out in transition to avoid tussling with set halfcourt defenses. That could favor Illinois (97th percentile) and Arizona (94th) as the top teams in transition offense with \u201cexcellent\u201d ratings from Synergy.<\/p>\n
