The problem with UVA's pack line defense is that you need to think about it like a zone at times, even though it also involves man principles. For example, if someone like Lykes or Newton beats the defender off the dribble, they should expect the "pack" to be in position to cut off the dribble drive. Someone like Newton can be successful if the pack doesn't close out quickly and Newton stops to hit his typical shots in the lane. Otherwise, you need to think about it as comparable to a zone, in that the drive should cause the pack to defend the lane, freeing up the kick-out for an open three.
A second consideration is how UVA handles ball screens. They almost always have the screener's defender immediately pick up the ball handler, to avoid the quick drive to the basket off the screen. Moreover, UVA often has the ball handler's original defender stay with the ball as well to create a double team. Unfortunately, we haven't handled this well in the past, and infrequently were able to find the screener on the roll. I also like to see teams that, instead of completing the screen, use it as a decoy and have the ball handler drive to the basket immediately prior to the screen. Someone like Lykes with his quickness could take advantage of UVA overplaying the ball screen.
The teams that I have seen operate successfully against the pack line defense also attack the pack with lots of off-ball screens. In that case, defenders can't simply sit in the pack, but instead need to respond to the screens, which may create wide-open threes if the offense is moving the ball. If the defenders respond to be in a position to contest threes, that should open up the lane to permit better dribble penetration and shots at the rim. But you need lots of movement. If out half-court offense tonight consists of one, two or even three-player movement, with the remaining players merely spotting up (with no movement), we will be looking at another sub-50 point game and an easy UVA victory.
