16. Luc Mbah a Mounte
Last year the Houston Rockets were one of the best defensive teams in the NBA, in large part due to the work of Luc Mbah a Mounte. Mbah a Mounte averaged 1.2 steals per game with the Rockets and they fell just one win short of the NBA Finals.
Without Mbah a Mounte this year, the Rockets defense has not been playing at a high level. The Rockets sit two games under .500 and are currently 13th in the Western Conference.
