For most of the season, Kawhi Leonard was having one of the quietest MVP campaigns in recent memory. That changed on Monday night when Leonard scored 39 points as the San Antonio Spurs fought back from a 16-point deficit to beat the Houston Rockets.
In the game’s final 30 seconds, he single-handedly secured the 112-110 win with a soon-to-be legendary sequence where he put the Spurs ahead with a three-pointer and then raced to the other end of the floor to block James Harden’s potential game-tying lay-up. The win helped the second-placed Spurs keep pace with the Golden State Warriors, while igniting a long overdue discussion about Leonard’s place in an incredibly competitive MVP race.
