There really is no reason not to modernize officiating. With all the cameras you could have 21 or 15 officials in a booth, 3 watching each area of the field or specific matchups, buttons in front of them with every possible penalty. They can make calls almost instantly. If 2 of 3 press their penalty button it immediately goes to the referee on the field and he can throw the flag and announce the call.
That’s just one crazy, but I think doable, idea off the top of my head. There’re so many options to make officiating better with modern tech it’s ridiculous. There’s no shortage of money to do it.
(Also, make the officials explain all of their calls post game and mandate availability to the press.)
