An overtime game is, by definition, close. The Dallas Cowboys managed to end regulation tied with the Houston Texans before they lost due to a combination of failed execution and, in hindsight at least, a really bad coaching decision on fourth-and-one.
But the truth is, it wasn’t really that close, as the Texans outgained and outplayed the Cowboys almost the entire game. Only some really boneheaded calls of their own plus some big defensive plays at just the right moment kept Houston from winning it pretty handily. They moved the ball up and down the field, mostly at will, while the Cowboys had the same problems with third down conversions and settling for field goals that we have seen all season.
