Virginia Tech's offense is built around the 3-point shot. The Hokies are in the top 50 in 3-pointers attempted and make the eighth-most per game (10.4) so far this season.
With UNC's scoring struggles, it's become imperative for the team to sell out on defense, so the team doesn't get caught on the wrong side of the math game.
That means locking down VT's Jalen Cone, who is shooting a wild 55.7 percent from deep this season and who went 4-8 from 3 against Syracuse last Saturday in his first career start. Landers Nolley II is also shooting 38.3 percent while taking on the brunt of the Hokies' scoring load (17.8 points per game).
Take advantage of size
The one thing teams can't take away from UNC is its size — the Tar Heels have been a "good, not great" rebounding team this season, according to Roy Williams. Offensive rebounding from Garrison Brooks and Armando Bacot has been one of the few things buoying the offense when UNC goes on a dry stretch.
Against Syracuse, Virginia Tech didn't start a player taller than 6-foot-7. The Hokies tallest player, John Ojiako (6-foot-10), hasn't cracked double-digit minutes in the past four games. North Carolina needs to press its advantage and try and rebound every time a shot goes up, and draw fouls with its size.
Brooks has been a steadying force for North Carolina, and the small Virginia Tech team shouldn't pose problems if he can get the ball man-on-man in the post. It'll be up to Bacot to find some consistency, stay out of foul trouble and punish VT for its lack of size.
No second half runs
The first 10 minutes of the second half seem to be UNC's Achilles' heel this season. Gonzaga, Yale and Pittsburgh have all punished North Carolina in the opening minutes of the second half, leading to some bad losses and one close win.
UNC has been anything but consistent this year, and the team has wilted after taking its opponents' best punch. Finding a way to counter when a team goes on a run and staying composed on the court are the biggest challenges North Carolina needs to figure out for the rest of this season.
Virginia Tech brings plenty of firepower — the Tar Heels need to find a way to not let that scare them.
