On the field, the officials ruled it a touchdown. The guy in the booth had a different interpretation.
According to NCAA rules, touching the pylon is out of bounds. Oddly enough, if he had dove over the pylon, it would have been a touchdown. A player is out of bounds if any body part is touching a sideline, end line, or anything, other than another player or a game official, that is on or beyond a sideline or end line. That “anything” includes the pylon.
RULE 4: Ball in Play, Dead Ball, Out of Bounds
SECTION 2. Out of Bounds
Player Out of Bounds
a. A player is out of bounds when any part of his person touches anything, other than another player or game official, on or outside a boundary line (Rule 2-27-15) (A.R. 4-2-1-I and II).
b. An out-of-bounds player who becomes airborne remains out of bounds until he touches the ground in bounds without simultaneously being out of bounds.
c. A player who touches a pylon is out of bounds.
Held Ball Out of Bounds
A ball in player possession is out of bounds when either the ball or any part of the ball carrier touches the ground or anything else that is out of bounds, or that is on or outside a boundary line, except another player or game official.
RULE 8: Scoring
SECTION 2. Touchdown
ARTICLE 1. A touchdown shall be scored when:
a. A ball carrier advancing from the field of play has possession of a live ball when it penetrates the plane of the opponent’s goal line. This plane extends beyond the pylons only for a player who touches the ground in the end zone or a pylon. (A.R. 2-23-1-I and A.R. 8-2-1-I-IX).
In conclusion, they got it right. The real amazing thing is how quick on the trigger the review official was on this play, when he/she fell asleep when a Mizzou player clearly trapped a ball that was ruled a reception. But that is a rant for another Sunday morning...
