From Tom Pelissero at the Press-Gazette:
This was as straightforward a game plan as Capers has put together. The Packers played 60 of 77 snaps (77.9 percent) in nickel against Scott Linehan’s three-wide offense. The rest was base (16 snaps) and a single snap of prevent — no dime, no "corner Okie," no "big Okie," not even any goal-line defense as the Packers made a pair of key red-zone stands.
The blitz package wasn’t extensive, with extra-man pressure coming on only 11 of 47 dropbacks (23.4 percent) even as the Lions threw heavily in the fourth quarter. Slot blitzes were especially rare with CB Jarrett Bush taking Woodson’s usual spot in the nickel.
The secondary did most of its damage out of basic zones, with FS Nick Collins exploding from Cover-2 to record the first of four interceptions and CBs Tramon Williams and Woodson each getting one in quarters coverage.
As good as QB Matthew Stafford looked against the Browns, Capers must have watched the game film and saw that Stafford is still playing like a rookie QB. He mixed up the coverage a little, sometimes it was cover-2 and sometimes it was man coverage, but he didn't blitz much and he let his excellent secondary wait for Stafford to make a mistake. A good job by the coach to identify that his players could beat their players, and then to let them do just that.
