The video should be used as a backup in either case, not just a crutch. The emphasis should be on getting the initial call right.
It makes perfect sense that refs can't review a play that isn't called. A call creates a stoppage. If there's no stoppage, how can you review a play? The refs can't just blow their whistle and stop the play after a controversial no call to check the tape.
Lets just say there's a blatant goal tending that is not called, and that 'block' leads to a fast break score... You can't reverse that play and take away the points that were scored because you missed a call 10 seconds earlier. The only way a play can or should be reviewed is if a call is made in the first place.
