His leg propped up on another chair, he watched his teammates practice without him. Throughout it all, he repeatedly urged freshman Jaron Hopkins to talk and speak up on the court.
There are a lot of things CU misses without Dinwiddie on the court, but his ability to direct the team and have his voice heard during critical moments might be one of the important things the Buffs miss.
Hopkins, who took Dinwiddie's spot in the starting lineup at point guard, is slowly learning how to fill that void.
"I'm working on being more vocal, because that's something I didn't have going through high school and the first part of the season," Hopkins said. "That's getting pretty easy for me."
Not known as a vocal player, Hopkins said the adjustment did not take him out of his comfort zone; it was just different.
"I think it's just more of a habit not talking," he said. "That's what I have to get over and keep working at it.
"I think I got too comfortable just taking a back set and listening to Spencer and (Askia Booker) and the leaders on the team. Now I have to step into that role and be a leader."
Statistically, Hopkins has struggled since taking over for Dinwiddie. In four full games, he's averaged 4.5 points, 0.8 assists and 2.8 turnovers, while making just 25 percent of his shots (6-of-24). He's 0-for-10 from 3-point range during those four games.
"I'm going through a tough time right now," he said. "I'm not really shooting the ball as well as I can, but with hard work and practice I think I can flip that around."
CU assistant coach Jean Prioleau said Hopkins can't be judged on his statistics, though.
"It's not about the statistics offensively," Prioleau said. "He's doing fine. It's a process and that process takes time.
"He's coming along."
