The way they might get to where the need to be is the way they have sometimes in the past, with a defense that gives up a lot of yards, but gets a lot of turnovers. Even last year Randall showed a sense for interceptions, until he was hobbled. Dix has a knack for it. Rollins did in college, and showed some sense for it in 2015, though seemed to get fooled more than anything last year. With Jones's speed and quickness, I could see him getting his share, and the tall CBs like King, Gunther and House always seem to have a few, even though Gunther did not last year.
If the Packers can win the interception battle by at least about 3:1, the defense might be OK even if it gets chased up and down the field a lot of the game.
