Or BS DPI calls like the one against Tre? I'm sure there would be downsides, but teams should be able to use challenge flag (maybe once per game, and included in current total of red flags) to challenge a penalty. A panel of 3 people (in NY or somewhere) would have 3-4 minutes to review all footage and make a final decision. Something like that. And if refs knew they could be challenged, it would incentivize them not to make ridiculous calls. Just my 2 cents.
