If you all have been paying any attention Schwab has been on the Panthers bandwagon from even before the start of the season. And Cam absolutely sold the penalty (or flopped, call it what you want.) But guess what, the defender made it easy. Any QB with half a brain was going to take full advantage right then, and there's absolutely nothing wrong with that.
I didn't see it as a flop, he kinda slipped on the way down and the fact that the Dolphin player gave him a little push at the end of the play definitely didn't help him.
