Up til this week, I did not give as much credence to the "4 and 2" notion, because in spite of the refs, The Broncs still could have made enough plays to win those games on their own. And sometimes the difference between champions and those just behind is a very fine line, but usually defined by one team's "will to win".
But now that the team is in position to make a more serious playoff visit, yes, the fact they are in the hunt AND lost some close ones, makes them more credible, to me anyway. I still don't give them credit for wins they never achieved, but it's more along the lines of, this team has been in tight, and are now learning how to win again.
