The Seattle Seahawks didn't want to do it. General manager John Schneider and head coach Mike Macdonald looked at their secondary this past offseason and decided there wasn't a cornerback worth choosing high in the draft, but there wasn't a free agent they truly liked either.
Still, going into a season with Devon Witherspoon, Riq Woolen, and Josh Jobe was a little iffy. Witherspoon is great. Jobe is better than expected. Woolen is an inconsistent mess who could be great for two weeks and then terrible for three.
But Shaquill Griffin hadn't been picked up in free agency, and the third-round draft pick for Seattle in 2017 might still have a bit left in his career.
