Thanks to Danny O'Neil at the Seattle Times for this article.
The Hawks signed Matt Overton, a long snapper, according to Overton's agent. Overton attended Western Washington, and this past season played for the Florida Tuskers of the UFL. Overton received a tryout with the Seahawks at a rookie minicamp in May 2007. If you click on this link here you can see Overton has a YouTube Snap Shot that is pretty awesome.
Overton is currently the one Long Snapper on the roster at this moment. That could change when free agency opens up and the draft takes place.
