Here is an article on Bulls point guard Derrick Rose and his leadership progression. Many of the quotes are from Bulls head coach Tom Thibodeau:
Several times this season, Rose has said he enjoys Thibodeau's intensity and that Thibodeau knows he can yell at Rose because Rose, who is equally intense, can take it. "You say scream. I say coach," Thibodeau said.
"When your best players are coachable, it makes your team coachable. That sets the tone for everything. The way he works and studies and is never satisfied and is so unselfish and totally into winning, that's what makes him so special.
"When you have a player with that talent that has those intangibles, it makes your team special. A big part of leadership is helping sell the vision of the team to teammates. He does that by example and he's being more vocal now."
