Utah Jazz just did it recently against the Golden State Warriors. They blow a 21 points lead in that game. Overall, they only win 3 out of their 10 last games.
They blew their lead again on their game today, they were up big in the 4th quarter but they allow the Suns to have a good run, and as a result, they lose the game. This team has no chance in the playoffs if they won't play great defense.
