Jackson was Seattle’s starting QB in 2011, but let go last season after Russell Wilson won the job.
He signed with Buffalo, where he didn’t play in 2012, and then was released on Monday, spurring speculation that he might sign with the Seahawks.
Seattle had appeared content to go with Brady Quinn as a backup to Wilson. But Jackson’s experience as a starter in the offense, his familiarity with the coaches and personnel, and his running ability, might make the team think he is a better fit for the job.
The Seahawks are in a mini-camp through Thursday and the assumption would be that if he is to sign, he would so by the end of that camp.
