One thing I think you need to do though is separate the 'team' from the individual. Yes it might be a little silly to claim accomplishments from what in reality may have been a poor performance. But is it relevant to any one individuals future on that team. I say no. If a coach wants to 'inflate' his team a little so be it. As long as privately he lets each of his players clearly know where they stand from a future perspective. If he is telling a kid who throws 72mph that e everything will be fine and he is right on track for a college career then that is wrong.
