I'm going to take the optimistic approach and say that Hollis came in, didn't do anything on the spur of the moment and reviewed everything thoroughly before making changes.
You can say what you want about the firings and the new guys brought into the board, but the bottom line is, it's the 11 guys we put on the pitch each game that really matter. Obviously anyone involved in assembling this squad have a lot to answer for and I can only assume from the recent changes, Hollis didn't like what he heard and shook things up.
Only time will tell.............
