It seemed that Rodgers let him know about it, whether it was the drop, or if Kuhn ran the wrong route. It doesn't really matter but Rodgers' facial expression has that he seemed pissed off, and he had words with Kuhn after the play. To me, Rodgers allowed his frustrations to come through after that play, he may be a perfectionist, but he needs to keep his composure, and that is a lot to ask but it doesn't look good.
Yea Brady and Manning do the same thing and I have no problem with Rodgers doing it.
