With replay I'm torn. Either throw it away and accept the officiating is flawed or use as much technology as possible to make officiating automated.
Part of me misses the old days. If there was a bad call a make up call was on it's way. Sure the system was flawed, but there were equally flawed measures built in to correct them. Refs also operated with confidence, unless they blew so many calls the fans would be yelling at them. The current system has refs acting cowardly almost by design because it's easier to let replay handle the hard decisions.
The problem is we can't move backwards with replay. Now that we've debated for months about a catch/non-catch (Dez Bryant in the playoffs) we just can't go back to seeing a bad call and not immediately changing the rules. Add in that social media can run with anything and it's just a hot mess.
Let's just have robots be refs. Eventually some roided out player will lose his poop, attack one of the robo-refs and that will begin the human-machine battles that will follow:
