I believe they’re doing 2 minutes in college football, but 1 really should be enough.Not a shock, though I didn't hate the concept. The PI review as it was executed was a joke.
I maintain that all replays should have a 60 second clock, at which point the review screen/booth automatically shuts down. If the official saw enough to overturn the call, then do so, if not, the call stands. It's rare that reviews that run longer than that are ones that are clear and indisputable.
