The defense was notably used in the 2019 NBA Finals between the Toronto Raptors and Golden State Warriors. The Raptors utilized a box-and-one defense with reserve shooting guard Fred VanVleet late in Game 2 in order to shut down Steph Curry as he was the lone offensive scoring threat once Klay Thompson left with an injury and Kevin Durant was ruled out. This tactic prevented the Golden State Warriors from scoring for over five minutes. The Raptors were narrowly defeated despite having given up an 18–0 run at the start of the third quarter. In Game 4, the Raptors once again employed the same defense in a 105–92 win to take a 3–1 series lead. After Thompson was injured in Game 6, the Raptors again employed the box-and-one with VanVleet against Curry and won the game to win the championship.
