Circling back to the Walt Anderson presser. here is a summary of the 2016 rule changes.
- Technology for coaching purposes
Coaches can use video images, photographs and computers for coaching purposes in the press box and locker rooms. They are not allowed on the playing field or sideline. Game management is responsible for assuring identical television capability and identical internet connectivity in the coaches' tooths of both teams.
- Sliding ball carrier: Defenseless Player
​"A ball carrier who has obviously given himself up and is sliding feet-first".
A sliding ball carrier is now protected under the defenseless-player portion of the targeting rules. "When a ball carrier goes into a feet-first slide and gives himself up the ball is declared dead at its forward-most point where he obviously beings his slide".
- Length of charged timeouts
​A charged team timeout shall be 30 seconds plus the 25-second play clock interval. However, the head coach may request that one of the allowed three timeouts in each half be a full timeout. This request should be communicated to the referee when the timeout request is made to the officials. The charged team timeout during an extra period may be a full timeout, at the request of the head coach.
​Blocking below the waist was previously allowed from tight end to tight end, it has now shrunk to the tackle box. Players on the line of scrimmage completely inside the tackle box, and stationary backs who are at least partially inside the tackle box and partially inside the frame of the body of the second lineman from the snapper can also legally block low.
- Unsportsmanlike conduct by a coach
​Any coach, player, or identified squad member in uniform who commits two unsportsmanlike conduct fouls in the same game shall be disqualified. A coach disqualified from the game must leave the playing enclosure within a reasonable amount of time after the disqualification, and must remain out of view of the field of play for the remainder of the game.
​The replay official shall review all targeting fouls. The replay official may create a targeting foul only in egregious instances in which a foul is not called by the officials on the field. Such a review may not be initiated by a coach's challenge.
