New England's Ben Watson strikes me as more of a receiving tight end than a blocking threat, but the Seahawks would be better for his presence. They're expected to visit with him, ESPN's Adam Schefter tweets.
Seattle already has John Carlson, but so what? The second tight end spot hasn't been a strength. Watson would help the team's depth at the position.
It's always tough to tell how serious a team might be when it lines up visits. This could be a look-see or it could quickly develop into more. Watson's return to the Patriots appears to be a longshot, Mike Reiss of ESPNBoston.com notes.
