CLEVELAND— Jets head coach Eric Mangini blamed "a lack of attention to detail" and the "long shadow of our franchise's historical mistakes" for Sunday's poor showing against the Browns, noting that a long-lamented missed PAT from 1979 had finally had enough of a negative effect to cause a Jets loss. "I remember when Frank Gifford was calling that game, he said that missed extra point would cost us later on," said Mangini, who said an underperforming offense was also a minor factor. "I mean, I was only 8, and the Jets beat the Dolphins 33-17, but I knew it was just a matter of time." Jets quarterback Chad Pennington said he had also felt the 27-year-old miss hanging over his head, particularly during the fourth quarter of the game and the late 1990s.
