I'd just like to point out that teams don't 'game plan' against their opponent like they do in regular season games. The object here isn't to win or lose, it's to test out your players and the team in general.
So the whole 'who cares its just 'preseason' argument is valid because BB and the coaches did not develop a game plan to win, it's all about testing your players out and identifying who's staying, who's leaving, and where the problems are before regular season starts. It's also a chance for players to prove their skills, get taped on some game footage so if they don't make this team other teams might see them and be interested.
