Prior to the final drive the refs added 2 secs. At the time it seemed ike a good bro move by the refs.I’m more surprised that a FG of 54 yards only takes 3 seconds. Snap it, put it down and travel 54 yards. Seems like that would be about 5.
If they didn't add those secs the game would have ended on the kick off. Non factor in the end.
