#2 - The public comments about Buzz were foolish and showed a remarkable lack of organizational understanding and leadership. Whatever the pissing match between Buzz and LW may have been, and regardless of who was more in the right in the "whole story" situation, Buzz never aired the grievances publicly (until he left MU, of course).
#1 and #3 go hand in hand. And, unfortunately, the same lack of awareness and leadership that created #2 are what made #1 and #3 so obviously present in LW's tenure.
Trust me when I tell you that #2 did not affect LW's complete inability to politic in the proper manner with the BOT and the major donors. The big players behind the MU curtain couldn't care less about #2. But, #2 was another piece of evidence exemplifying LW's lack of leadership skills from a fundraising and politicking point of view.
Let's face it; the AD at a major university with a strong athletic presence can't just be good at directing the athletics. He has to be the face of the department. He has to know when to kiss rings and know how to kiss rings. LW had none of that charm or gravitas and whether you like it or not, same is required once you get to that level.
You can't be a major level AD and not know how to play the game. LW did not know how to play the game.
EDIT: As a side note, LW will never receive enough credit for some of the good things he did. That said, he was, in many ways, a bumbling Neanderthal when it came to slimier side of the business.
