I rewound and watched our final possession against Xavier. It looked like Crawford immediately made a mistake by getting guided to the right sideline. We had some action on the left side of the court, but instead of Crawford swinging the ball to Woods at the top of the key, Woods was forced to go farther to the right, and away from where the play was developing. He got the ball on the right side, couldn't get it over to the left where Dinos and Arians were setting up, and ultimately just gave it back to Crawford.
It's a little more complicated than just "run a set." In late game situations, defenses switch everything and do everything they can so as not to give up an open shot. When you need a 3, there is no such thing as a real mismatch for the defense. A center can guard a PG when he knows he is looking for a 3. In my opinion, your best bet is to try and create confusion and hope they mess up a switch. I'm not saying there isn't room for improvement in our late game strategies, but when you don't have guys that can create their own shot, then it takes someone with a greater basketball mind than mine to figure out how to get them open when the defense is switching everything.
Personally, I like double screens that break into single screens (have 2 guys set a pick for 1 guy, then one of the screeners turns and sets a screen for the other screener). Just try and create as much confusion as possible, especially since we have a big that can shoot 3's.
