Moffitt, a 2011 third-round pick out of Wisconsin, started nine games before a knee injury ended his first season. He recovered and started six of eight games he played last season, as well as two playoff games.
Moffitt got into some minor trouble in the spring over urinating in public, but showed back up to camp ten pounds slimmer and ready to fight J.R. Sweezy for a starting spot.
Moffitt said there were no "bad feelings" about the trade. "At the end of the day it’s a business, it’s money, it’s X’s and O’s, it’s who can you get and who is worth what." Moffitt will play for Cleveland at guard in an offensive line beset by injury.
Sanford, who is entering his fourth year, has only played six games -- just one last season. Still, the former Temple player made a sack along with three tackles in two games to start off the exhibition season, and the Seahawks have listed him as left defensive tackle.
Seattle also signed undrafted free agent Dewayne Cherrington after a tryout last week. The 6-3, 335-pound tackle played at Mississippi State, and was briefly on the Patriots' roster before being released in June.
To make room for Cherrington, Seattle waived kicker Carson Wiggs, a free agent from Purdue.
