First, they used DM as a decoy. DM drove to the middle, drawing the defense to himself, then he lobbed to a wide open Rudy who slammed it in, putting the Jazz up by one with 11 seconds to go.
Second, the Jazz double teamed Docich, forcing him to pass instead of shooting it. The Mavs then missed the final shot, the Jazz win.
The Jazz’s played the last two plays perfectly.
However, if the hadn’t missed half their free throws, they probably would have won easily.
