TV coverage of replays

I posted someting like this in the game day thread but want to know if others have noticed the lack of good replays of some critical plays.

In the past is seemed like there were replays of almost evey play and multiple replays of critical/questionable plays but now sometimes there are no replays of even critial/questionable plays.

Also it would be nice if the play-by-play guy would say "flag in the defense backfield" or "flag in the offense backfield" instead of just "there's a flag". For some reason this really bothers me.
