I am pointing out that his stumbling and bumbling in interviews is one of many examples of his lack of attention to detail and discipline (which also reflects in the MANY game and on the field examples shared in this thread and others). If I was the face of any major program or company and I had poor interview or PR skills, I would certainly invest time and effort to improve. Successful coaches or CEO's instill a level of confidence that they know what they are doing by what and how they communicate. Does anyone question whether Sean McVay knows offensive football? I can't think of a better example of someone who, when they speak, leaves no doubt about their football genius, and furthermore, proves it on the field through his team.
What you put out to the public in a position like Kalani's is a reflection of who and what you are and what you represent.
