It’s mid-November, and Cousins is not only still here but also very much a part of the Lakers’ operation. On Monday, he was back in his usual seat for the Lakers’ 114-104 win over the Spurs — at the end of the bench as a vocal, visible and, according to his teammates, valued presence around the league’s best team. “He’s just been a great guy for us, being around the team,” Anthony Davis said. “Even though he’s not able to play, he’s always involved in practices and shoot-arounds and stuff like that as much as he can.”
