It’s the first day of NFL free agency, and the Seattle Seahawks are getting more than they bargained for. Lots of things are going down, and many players could be on the move in and out of Seattle.Two free agents are taking a look up at Pete Carroll’s team. Quarterback Chad Henne is taking a trip to the Pacific Northwest.You can add another team to Chad Henne’s tour: He’ll also visit the Seahawks, a source tells me. He already has a visit scheduled with Jags.— Jeff Darlington (@JeffDarlington) March 13, 2012Getting a quarterback like Henne could be critical to the Seahawks overall quarterback depth, as Seattle doesn’t really have anyone behind Tarvaris Jackson.Defensive end Jason Jones (who last played with the Tennessee Titans) will also be taking a look.Jason Jones will also visit the Seattle Seahawks.— Terry McCormick (@terrymc13) March 13, 2012Two former Seahawks are also being pursued. Tight end John Carlson is getting plenty of offers from everywhereIn addition to his visit with the Chiefs, TE John Carlson receiving interest from several teams: Bucs, Colts, Cowboys and a few others.— Adam Caplan (@caplannfl) March 13, 2012Might be tough for Seattle to keep Carlson around.The New Orleans Saints are going after one of the Seahawk linebackers.Saints are sniffing for LBs as well: Hearing they have some interest in MLB/WLB David Hawthorne.— Adam Caplan (@caplannfl) March 13, 2012To discuss Carlson, Jones, Henne and Seahawks fans, head on over to Field Gulls.
