As far as I know/remember, Baker had no character concerns coming out of the draft and was one of the best CBs in college. So no, you can't blame Gettleman for a guy going full stupid during this pandemic, especially a young player. You think people blamed the Pats for drafting Aaron Hernandez?? Steelers for Antonio Brown?
That being said this is a crushing blow for the Giants and moreso Seattle, who were relying on Dunbar to be their starting right cornerback with very little in depth in the secondary. At least Giants have a lot of depth at CB; Sam Beal probably gets the starter job by default over Ballentine and Julian Love, with Darnay Holes at slot corner. Seattle may need to try and pickup Logan Ryan.
