Suspensions aside, flops don't work if refs don't call them. The officials need to stop guessing based on reaction and start only calling contact they actually can see. At least Draymond got brushed with the elbow and exaggerated, Barnes completely invented the contact.
Similar play when LeBron got hit in the face last night - he really did get hit but the ref clearly missed the contact and only called it from his reaction. Stop guessing!
