Fred Thomas (hamstring), Colston uncertain

Sort of. It explains the game plan which, from Thomas' actions, seemed to suggest he expected Safety help on almost every play.

It doesn't explain what happened to said safety help though.

We were scratching our heads when Payton picked up about 90 safeties this offseason and drafted Harper in the second. Doesn't look like a mystery now. Safety appears to be a key cog in their system.
