On any individual person(s) breaking down an opponent. You stress a defense with: 1) the threat of shooting to pull away from the basket 2) passing to move side-to-side 3) screening to occupy secondary defenders 4) spacing to pull from the gaps Not one mention of putting the ball on the floor You're also a little mistaken about the positional versatility of who is considered a 4 this season. UVA won't see a single minute from John Camden unless Beran, Long and Nickel are hurt. Beran can play the four, but likely sees his most minutes at 5. Long can play on the wing, but likely sees most of his minutes at the 4. So if Ryan Dunn is going to have success, he's gonna be put into a million screens with Beran as the screener and have to recover to a great shooter. If he's guarding Long, then he will be defending a quicker version of Mutts who will look to isolate Dunn on an island and take advantage of the space. If he's guarding Nickel then he has to run off of a million screens to chase him around the perimeter...as a 4. If Ryan Dunn can do those things to 3 very different athletes and it be considered an "advantage" then he will be starting for some NBA team next season ...Ryan Dunn will not be starting for an NBA team next season
