Is the game broadcast with a delay?

Do the announcers have real time info?

Yesterday, 4 or 5 instances where seconds before a ball was snap, the annoucers said something. I was at the game, but then watched the DVR when I got home.

1 - when talking about the Giants field goal try, stressed it was their first of the year, and then mentioned how even though DeOssie is reliable, things happen. Then they bad snap.

2 - Before first INT, right when Fitz was snap the ball, they said the Giants D hasn't forced a turnover, then the INT.

3 - Before the fake punt, same deal, 2 seconds before the ball was snapped, they commented on Houston RB Blue being in.

4 - Before Cruz and his first bug catch, they mentioned he hadn't done anything, and then they were like there it is.

And the list goes on.

Is it luck? DO they just keep saying stuff, and somethings are right? Are they that talented at reading plays?

or

Do they have a delay, 4 or 5 seconds, and get fed info from the game in their ear or something.
