Reviews need to be limited in time. 45 seconds to change it or the call stands
A little insight to your idea:
Replay monitors are automatically in a 2-3 second delay. Now, ESPN has gone to remote production as opposed to being produced at the site. This adds another 3-5 seconds to the time the RO has to look at a shot. If you said 90 seconds, I could agree with it.
And, with the number of teams trying to go to NASCAR offenses, sometimes, with the tv delays, there are a lot of shutdowns that turn out to be unnecessary due to the fact the RO just hasn’t had time to look at the catch/no catch, fumble/down by rule types of plays.
There isn’t an RO or Supervisor in any conference that wants to go longer than 90 seconds.
In addition, in an effort to be 100% correct, which is expected of RO’s, collaboration with somebody in a command center has shown to make a review take longer as now there are more people looking at it. It’s like it’s become a committee now has to be involved and we know what a poop show that can become.
With everybody watching on tv now thinking they are experts, there is more stress and pressure in the booth to “get it right” it has become a very difficult job. Getting a call right takes precedent on getting it done quickly!
Just my 2 cents.
