It could be argued that Seattle’s strongest draft ever was 2010. Or 2012. Or 2011 if we only count defensive players. Those classes were so good it just depends on your favorite player, really. Seattle followed that run with the weakest draft in the Schneider/Carroll era, 2013. Only Luke Wilson emerged as a consistent contributor, with top picks Christine Michael and Jordan Hill vastly underperforming their potential.
As good of a stretch as 2010-2012 was, 2013-2016 was equally disappointing. For the purposes of this discussion, the thing that really sets apart an average draft from exceptional draft are those bonus late-round selections that turn into surprisingly good players.
