A lot of people (and frankly I thought this for a long time) assume that when a player goes out of bounds the clock stops in the NFL.
That is actually incorrect, as Larry Brown Sports points out the clock only stops the last 2 minutes of 1st half and last 5 minutes of 2nd half.
When Hakeem Nicks stepped out of bounds with 5:13 left in 4th quarter, Peter King shot off this Tweet.
Here is the official rule.
With the exception of the last two minutes of the first half and the last five minutes of the second half, the game clock will be restarted following a kickoff return, a player going out of bounds on a play from scrimmage, or after declined penalties when appropriate on the referee’s signal.
We will see if King apologizes, but I doubt it. Crazy to question someone’s intelligence when you don’t know rule yourself.
