The Defensive Gamble That Could Swing Illinois vs. UConn in the Final Four

The Illini defense has been stout so far in the NCAA Tournament, but it will need to step up again for Illinois to take down the Huskies

To win basketball games in late March and early April, sometimes you have to think outside the box. Illinois has already done that on its run to the Final Four, unveiling a completely different pick-and-roll coverage against Houston in the Sweet 16 before turning around and smothering Iowa in the Elite Eight.

But now comes the toughest challenge yet. Dan Hurley and UConn are waiting, armed with one of the most difficult offenses in college basketball to prepare for and a coach who always seems to push the right buttons. So if Illinois wants to keep this run alive, maybe it's time to throw another wrinkle at the Huskies.

Illinois could roll out a new defensive look

The Illini defense – deploying mostly man-to-man schemes – has been terrifying so far in this NCAA Tournament, a sharp contrast to what we saw at the end of the regular season. But to reach another level against UConn, Illinois should seriously consider pulling the pin on a zone.

The drawbacks are obvious: Zone schemes can be vulnerable to outside shooting and can sometimes turn rebounding into a group project that nobody is motivated to finish. But Illinois is uniquely positioned to handle both concerns.

For one, the Illini are generally fine giving up threes as long as they are dictating who takes them, ideally (and obviously) weaker shooters. As for the rebounding issue, Illinois is the tallest team in the country and should have no problem holding its own on the glass – even in a zone – against an undersized UConn team.

The benefits of a zone in this matchup are more interesting. It could take away a lot of the actions UConn loves to run. The Huskies are excellent at using misdirection and making defenses move all over the court. They also have a way of forcing teams to chase nonstop, which is a great cardio plan but not always a great defensive approach.

In a zone, though, Illini defenders could be selectively aggressive, avoid running after shooters around screens and instead have defenders waiting in the right spots. Additionally, Illinois’ length could make passes tougher and shots more difficult because the Illini can close gaps better than most teams.

Illinois on SI take

Illinois does not need to operate in a zone for 40 minutes, and it arguably shouldn't. But in a game this big, against an offense this polished, throwing UConn a different look – and maybe an extended one – could be worth the gamble. The Illini have the size to rebound out of it, the length to make passing lanes uncomfortably tight and the defensive versatility to at least keep Dan Hurley on his toes.

This late in the Big Dance, surviving is often about finding the right wrinkle at the right time. For Illinois, zone defense might not be the singular answer, but it could be the curveball that helps keep this magical season alive.
