Second is incumbents competing for jobs. If Souza is taking the reins and, if he is bringing in two new assistants, they need to be ruthless. Impart the message to some of these slackers or,guys who just can't cut it that you are not going to play. Either leave for D3 or expect to wear a suit in the stands for the better portion of the season.
The most important part of Souza's career starts right now. He blows this and he is a short termer. But, best of luck Mike.
