It is what it is. Good teams can overcome those bad calls. I'm not saying the Steelers are good by any means and calls like that hurts this team.
The NFL has become a complete joke with regards to this. It seems that anytime the pass is incomplete, they are looking for a pass interference even if the defender never touches the receiver. We've seen that a number of times in Pittsburgh alone. They really need to get a handle on this. Make the call if there is interference but for Fs sake, let them play a little.
