Per Detroit News, the Seahawks have signed long snapper Sean Griffin from the University of Michigan to a deal as insurance for Tyler Schmitt:
The reason for this move is most likely for precautionary reasons, but the Seahawks have not said anything about Tyler Schmitt's current state of health.This is perhaps a sign that the Seahawks are not completely reassured that Tyler Schmitt's back is completely fine .
Last I heard, Danny O'neil from the Seattle Times said on March 11th that the Seahawks expect Tyler Schmitt to be ready to play this season, and that Schmitt was training for the Seahawks' OTA's. I certainly hope Schmitt's back is OK. I don't want the Seahawks to be haunted by the ghost of J.P. Darche.
