If you didn't want to sound dumb, and save a little credibility, what you should have said was, "It's too bad that a few of the teams we thought were going to be good at the start of the year, were not. We were obviously much better than at least 7 teams on our schedule." That would have been a much more reasonable statement.
Instead, you went the stupid route and claimed that we had 7 built in wins on our schedule. That statement infers that we new before hand that we would easily win those games.
I'm honestly surprised that YOU are struggling so mightily with this concept.
