Kansas City Chiefs quarterback Patrick Mahomes said he's an advocate for a microchip or other technology to help officials make calls around the goal line.
Mahomes explained during an appearance on this week's WHOOP Podcast (via Pete Grathoff of the Kansas City Star) the number of players in a goal-line pile often makes it too difficult to make an accurate call from the sideline:
"I've always thought the chip in the ball has to happen sometime, where if you cross the line, it just tells you a touchdown. But it's also the human error thing. It's kind of like baseball, balls and strikes. It's just part of the game. The biggest thing to me is when they get in the pile by the end zone, there is literally no way to tell if he's in the end zone or not. It's like you said, it's just whatever they call. ... I'm sure it'll happen soon enough."
The idea of automated technology that alerts on-field officials when the ball has crossed the goal line has existed for decades, but figuring out a way to implement it is difficult.
Since the ball can reach the line in virtually an infinite number of ways based on how the ball-carrier is holding it and there are other factors in play, such as whether a knee or elbow touches the ground before the ball crosses the line, it'll be difficult to create a fully automated system.
That holds true in Mahomes' example because even if the technology can tell whether the ball itself reached the goal line, video review would still be needed to determine whether it happened before a body part touched the ground.
