I'm not sure what to read into this without knowing the numbers and contract lengths being thrown around.

I wouldn't be surprised if the agent asked for an outrageous dollar amount right upfront to see if the Packers would blink.
Jack Doyle (Colts) is projected to make $8M in 2017, $5.25M in 2018, $5.65M in 2019.
Not sure what Jermaine Gresham (Cardinals) signed for yet.
I certainly don't believe Cook is worth more than either of these two players.

This may be part of the game, but I guess time will tell.
