A couple of new snapping developments to report from the last few days.  The Steelers released Jared Retkofsky, who filled in for Greg Warren last season.  Warren and client Mark Estermyer are left to compete for the spot.  Two other Draft prospects, James Smith of Florida and Craig Gelhardt from Tulane, have reportedly been invited to mini-camp with the Bengals and Jaguars, respectively.  Finally, some positions players with snapping ability have also signed free agent deals.  Center Cecil Newton from Tennessee State signed with the Jaguars, while tight end Jamar Hunt from UTEP signed with the Cowboys.
