It’s the shared goals, shared vision, shared thoughts of the Miami Heat NBA Basketball Team. It is discipline, accountability, work ethic, and enjoying somebody else’s success. It is the hardest working, best conditioned, most professional, unselfish, toughest, meanest, nastiest team in the NBA. Everything they do is about winning. It’s not about anything else. So they ride with that. They think about that. It’s something they believe in. It’s for them. It’s not for everybody.
Everybody's given themselves to the team. Whatever the team needs, and there's no ego about anything right now. … That's Heat culture.
