-Having a single person game planning and calling plays might be "better" at the bottom line (hard to tell without knowing what the replaced process would do). The management challenge is what happens if expectations are not being met - that is the test of this type of decision.
-The "full time full control" O coordinator certainly means that the head coach has some more time and energy to focus elsewhere. Would love to know the answer.
-Doing exit interviews and doing something with the result is good news. However, it implies the same process was not in place before. Again would love to know about that too.
-The yoga thing again might help if anger was actually negatively affecting decisions or if Kelly thought it was. Always remember Vince Lombardi as someone who was the embodiment of an emotional coach whose decision making was unaffected. His players adapted by realizing his outbursts were not personal but rather about what they did or didn't do.
Found it instructive that people who teach executive management courses (like the Amer Mgmt Association) do not consider personality to be a critical aspect of effectiveness but have a list of some 20 core knowledges, skills, and abilities are their key factors.
To me personality is really most relevant when it affects how a person or organization functions in its environment. Over the years just about every coach in every sport I follow who went from the penthouse to the outhouse had perceived detrimental traits that often were there in the good times but become part of the "reason" for why a change was needed. In our world most would not care an iota what kind of personality a coach who won a BCS championship has until their team dropped out of playoffs and the big bowl scene. In our case the fan base seems to want a Tom Landry style and success until the time change is needed and then its Vince Lombardi
