I've seen a lot of speculation that the Packers are going to move Williams to safety, but I have a different theory. While I'm sure Tramon will play a safety role on some snaps, as he did a bit on Sunday and as Jackson has at times, I think Jermaine Whitehead is the guy who will see the big uptick moving forward.
On Sunday, the Packers were in dime almost 100% of the time. Williams, Alexander, and Clinton-Dix played 100% of the snaps, King played 97%, Whitehead played 96%, and Brice played 85%. That was a season high for Whitehead by a long shot. The staff has been talking him up since camp, and he's come through for them in the early going. I remember Pettine making the comment before the season that Whitehead is the most cerebral player in the secondary, which is something that Pettine's defense has always placed a premium on.
With Josh Jackson on the bench (as well as Bashaud Breeland, Josh Jones, and Tony Brown), my guess is that FO and staff see a DB surplus. I bet that we will see Whitehead take over as the starting safety and Jackson come off the bench to play in the dime. So instead of a dime package consisting of 3 corners and 3 safeties, it would be 4 corners and 2 safeties.
I have no idea if this will work or not, but that's my speculation as to what's going on. After mulling it over, I believe Pettine is down on Clinton-Dix, high on Whitehead, and the FO decided to get something out of the former while they could.
