Flopping???
 

Whether flopping or not, I'm not sure he was even out of bounds when hit. If so, his foot was so slightly over the line that I couldn't countenance a late hit call. The tackler is looking at the ballcarrier's upper body and couldn't possibly see the foot land out of bounds.

I didn't watch the game, but when you have a catch like he had, maybe you get at least one prima dona moment. ;)
