Well, you know what they say about opinions. Dave is doing just fine. He is an excellent manager and has put people whom he trusts and believes in, into positions that he feels they can better accomplish the goals of the office. Critics have it easy, they sit back and watch others work, while they risk nothing.
That is a load of crap! He does not even truely know any of his top people who were picked by the previous SA. With the exception of Johnson they don't even know the office. And contrary to what Dave has been told they all have a political agenda. Just wait and see.
