Turning his head, Randolph continued to score in the low post with a spin move and a hook shot off the glass.
In these two rounds, Hansen did not participate in the offense but instead played a restraining role on the weak side.
This was the "more stuff" Hansen was talking about.
During the starting period, the Grizzlies' offensive focus would be Randolph, while he would conserve as much energy as possible.
Conserve energy for what? Naturally, it was for playing during the bench linking period.
If you want to extend the starters' time on the court, it's not possible to extend it for all of them. Otherwise, by the decisive moments, they'd all be exhausted and there'd be no need to play.
Moreover, the bench linking period doesn't have too many set plays. Often it's chaos, and Randolph as a heavy inside player, isn't suited for that.
Around 7 minutes into the first quarter, Hansen was substituted by Tony Allen to rest.
