Most open 3 attempts come due to switching and/or help D with a good pass to the player left open due to the switch or help. On most of those a Vol dashes out but too late to be effective. A significant number of made 3's happen with a hand in the face. It's pretty much impossible to stop every 3 point attempt without risking a 3 shot foul. Tough to find the perfect balance between weak side help, covering the corner, pressing the arc, protecting the lane, and positioning for rebounds.
Contested 3's that are made are simply a part of the game. All they can do is all they can do. Too much focus on the arc leaves the lane less protected and negatively impacts rebounding. So far the tradeoffs have not been fatal.
Expecting totally consistent intensity is a bit much. There is only so much energy to be spent so the team has to pick its poison and timing. Every team has to work for more runs than the opponent and hope they don't run out of gas like Louisville vs Duke. Got to keep something in the tank for end game.
