It wouldn't be right to get too worked up after the Seattle special teams' wretched Week One effort, considering how big a strength the unit was in Pete Carroll's first season. But team insiders believe there's certainly cause for concern, primarily due to the ankle injuries that could keep special-teams co-captain Michael Robinson and rookie Byron Maxwell, who excelled on special teams in the preseason, out of the mix for a while. Robinson's injury is especially costly because he is also the starting fullback, as well as a key blocker in the run game. "Him being out just changes everything," said one daily team observer. "He's really become such a leader. He and Mike Williams are the only guys on the offense who were starters last year at this time." New PK Steven Hauschka's failure to kick a single touchback in Week One is another worry. "He kicked the ball in the endzone, but not out of the endzone," the observer said.
