In the first quarter of the Super Bowl, Pete Carroll challenged the ball spot on a third down run by Russell Wilson. The original spot was about a yard short of a first down. After review the ball was respotted about a half yard closer to the “line to gain.” So, the ball is repositioned, but no first down.
The thing I don’t get is that the refs then said Carroll’s challenge was unsuccessful, and so charged the Seahawks a time out.
Given that the spot was changed, why was the challenge considered unsuccessful?
