The University of North Carolina (UNC) men's basketball team has experienced a remarkable defensive transformation, thanks to several key tweaks implemented by head coach Hubert Davis. These adjustments have resulted in a six-game winning streak and a spot in the top 5 of the AP poll, solidifying the Tar Heels as serious contenders for the national title.

One of the significant changes made by Davis is having the guards stick with just one man off the ball, which has helped protect UNC's smaller guards, R.J. Davis and Cadeau. This strategy has limited the mismatches teams often hunt for against these undersized guards. Additionally, both guards have stepped up their individual defense, as evident in their impressive performances against opponents like Pittsburgh and Syracuse.

The defensive improvements extend beyond individual matchups. UNC has adjusted their ball-screen coverages while still utilizing Davis' preferred drop scheme. One notable change involves having the drop man, usually a big like Armando Bacot or Walker Kessler, playing higher up to touch the ballhandler. This adjustment has disrupted opponents' passing lanes and forced them into contested midrange jump shots.

The defensive tweaks have also had a positive impact on help defense and rotations. The players' trust in each other's ability to be in the right defensive positions has been crucial, as highlighted by Davis referencing a clip of Kevin Garnett's defensive insights. This improved trust and coordination have led to crucial stops and blocks, such as Quincy Ballard's well-timed help-defense block against NC State and strong help from Dawson High against Clemson.

Another area where the Tar Heels have seen significant improvement is defensive rebounding. The coaching staff's emphasis on this aspect of the game has paid off, as UNC now averages the most defensive rebounds in the country over their last five games. This has contributed to a reduced number of second-chance points allowed during their winning streak.

Graduate transfer Justin Ingram deserves recognition for his adaptability as he shifted from playing the three to the four position defensively. Ingram's rebounding prowess has been instrumental in UNC's recent success, with his two best rebounding performances coming in their last four games.

UNC's defensive resurgence under Davis has put them in rare company. Roy Williams, the former head coach, led the Tar Heels to a top-20 defense nine times, resulting in seven Elite Eight appearances and three national titles. Now, UNC is on track to achieve a season-long top-20 defense for the first time under Davis, fueling excitement and expectations for the team's championship aspirations.

With their newfound defensive prowess, UNC has emerged as a force to be reckoned with in college basketball. The combination of improved individual defense, strategic adjustments, and strong rebounding has propelled the Tar Heels into the elite ranks of the AP top 5 rankings. As the season progresses, UNC fans eagerly anticipate the team's continued defensive dominance and the pursuit of postseason success.
