Great thread. Just to clarify, Hurley's 3 did not clinch the game vs UNLV but brought Duke back into it. They were down 76-71 when he hit the 3. Arguably as big in that game was Brian Davis' And-1 to put Duke ahead 77-76.
These are my favs:
1. Laettner, UK 1992 is clear. After that?
2. Crazy Battier tip-in vs Arizona 2001 toward the end of that game.
3. tie: Davis' And-1 / Hurley 3.
5. Laettner buzzer beater vs UConn (this is #2 in some ways for me but the others helped secure national titles. But this may have been important to his confidence in the UK game).
6. Jones' 3 pointer vs Wisconsin.
7. Dunleavy's fast break 3 vs Arizona mid-late 2nd half. He hit several big shots but that one was a big momentum shot.
