(Renton, WA)  --  In the wake of the injury to offensive tackle George Fant, the Seahawks are adding even more depth to their depleted offensive line.  Seattle finalized a deal yesterday for Philadelphia Eagles' reserve tackle Matt Tobin.  The 'Hawks are sending a 2018 fifth-round pick to Philly in exchange for Tobin and a seventh-rounder.  The 27-year old lineman played in 42 games, starting 21, since arriving in Philadelphia as an undrafted rookie from Iowa in 2013.
