The Seahawks have made tenders to longsnapper Clint Gresham, safety Chris Maragos and defensive tackle Clinton McDonald; all three became restricted free agents on Tuesday as the new league year started. The Seahawks also signed K Carson Wiggs to their roster back on March 5th, per Liz Mathews. With starter Steven Hauschka possibly leaving in free agency, it makes sense that Seattle would look for a backup plan to develop. Source: SBNation.com
