There's a big difference between allowing open 10 footers and open 22 footers. If the defense is keyed on making the opponent beat you with 15-23 footers, which is the lowest-percentage shot in the NBA, and the opponent makes 60+% of them, it's still not a bad strategy. Yes, Boozer can play him closer, but I'd still rather see Hansbrough taking long jumpers all day than Hansbrough driving by Boozer all day and getting actual high-percentage shots. Watching Hansbrough play all season his best options are to shoot the open midrange jumper or drive in and get fouled. If you want to consistently let him keep taking the open jumpers when he's making them then you might want to rethink that strategy. He has trouble with length closer to the paint. Play tight so he can't get off the jumper and don't foul him when you're contesting his shot in the lane.
