When client Clint Gresham of the Seahawks signed his one year contract as a restricted free agent yesterday, free agency at the snapping position ended along with it.   Last week, Thomas Gafford (Chiefs), Tanner Purdum (Jets) and Andrew Economos (Bucs) each signed new agreements with their teams.  With these most recent transactions, every snapper has now returned to their team.  In total, there have been 13 new long snapping contracts since the end of the season.
