Is there any evidence of this? Did you see an argument on the sideline while watching the game with a lip-reader?
Rodgers was upset with Linsley on one play - Linsley confirmed that. And Rodgers was upset on a few passing plays but it's not always clear whether he was upset with himself or the receiver. IMO who he should have been upset with overall for that performance is himself: He was not sharp.
If the Packers believe their three best WRs, in order, are Jordy, Cobb, Boykin and if they believe the Seahawks best CB is Sherman, I honestly don't have a problem with them not going out of their way to throw at Sherman. If Rodgers were his usual pinpoint accurate self, Jordy, Cobb, the TE and the RB in the game at the time should have provided plenty of targets for an efficient offense.
