I didn't see any obvious holding calls that weren't called. I did find it amusing when Trubisky gets sacked and fumbled that the replay showed 2 facemasks. On the first one - the announcers said - oh he probably just touched it and didn't pull on it. Then the 2nd facemask occurs and it's uh yeah, that was after the fumble.
And of course you can't touch Rodgers. Nichols hits Rodgers in the shoulder...barely...and get flagged.
Packers offense is elite, but their defense could keep them from going winning the NFC.
