Brown was released but quickly brought back to the roster and is expected to still see time in 2 WR sets, especially with Metcalf battling knee issues. Meanwhile, Dickson's move to IR makes Dissly and Vannett next up on the depth chart. No one is really a safe play outside of Lockett, however, and we first have to see how the rest of the targets shake out.
SEA TE Ed Dickson - Week 17 Fantasy Football Outlook
Week 17 vs. Arizona Cardinals
Ed Dickson isn't a major part of the Seattle passing game but he seems to be the top tight end for Russell Wilson to go to. Dickson is a veteran who can make big catches. Although the results haven't been there, he still has some fantasy value. But not enough to consider a start for Week 17 as he ranks a low-end TE2.
