You could look it up.

Casey Stengel used to say it (among other things), and all these years later, Brian Daboll pretty much said it, without saying it, after his first season as the head coach of the Giants came to what he called a “crash landing’’ conclusion with a dreadful 38-7 playoff loss to the Eagles.

What Daboll said the other day, in so many words: Just because we had some success this season does not ensure we will build off that success next season.

Daboll still seemed a bit shaken by how it ended. He has been this way before, but never as the man in charge. He was a part of 24 playoff victories as an assistant coach or as a coordinator, and eight times, he was on the losing end, experiencing the suddenness of playoff elimination. In his 21 years in the NFL, he has learned to take the most recent result and not give it too much credence, good or bad, because it often does not represent the breadth of the season.
