"These are the moments that define an NFL quarterback. Late game. Down a score. The stadium jittery with nervous anticipation.

All of the great ones are measured by these moments. From Bobby Waterfield to Peyton Manning, Sammy Baugh to Tom Brady, the best quarterbacks find ways to march their offenses through the teeth of angry defenses in the scalding hot pressure of necessary fourth quarters.

They make plays at the times in games that seem most dire. Matt Hasselbeck did it here for a decade.

But it was apparent again in Sunday's swooning 23-17 loss to Washington that Tarvaris Jackson is no Matt Hasselbeck.

In a defining fourth quarter Sunday, after the Seahawks' defense uncharacteristically squandered a 17-7 lead and the team needed a lift, Jackson gave them nothing, not even a first down.

"When we got into going-quick mode at the end, we weren't very efficient getting our stuff done," coach Pete Carroll said. "I would think we would be better than that. T-Jack is doing everything he can, but we need to look at the film and see how he played and his decisions and things like that. But I know he's trying his tail off to get it done.""
