The backup center position has taken a backseat in importance over the years, but with load management and injuries both increasing recently, that can’t remain the case. In the case of the Houston Rockets where Clint Capela is playing heavy minutes, there’s always the increased chance for injuries or need for rest for the Swiss big man. Luckily, Isaiah Hartenstein has shown over the last few games that he can step in and bring something the Rockets haven’t had in a long time: an athletic, tall center who can play 25 to 30 minutes if necessary.
