It isn't called the Death Lineup for no reason. The Golden State Warriors started employing it in the 2014-15 season on their way to winning their first NBA Championship since 1975. That lineup, considered small at the time, featured Stephen Curry, Klay Thompson, Harrison Barnes, Andre Igouadala, and Draymond Green. Barnes was the tallest player at 6'8". The nearly-omnipotent Kevin Durant has replaced Harrison Barnes to make the game-finishing five even more dangerous.
The Celtics will go into Thursday's game against the Dubs with, at worst, a tie with the Houston Rockets, for best record in the NBA.
