An eye in the sky is needed but to be overturning bad calls, not calling more penalties.
The NFL has a flag problem. So many games I've watched this year were terrible because there were flags on every other play.
Defensive holding and illegal contact calls specifically are something that need to get fixed. It's getting our of control. These are huge penalties that are being called way too often. Unless it's egregious we shouldn't be gifting offenses free first downs.
