The thing is this. It's not a Chiefs conspiracy. The Chiefs are a really talented football team. They often put teams in situations like this where there are slim margins that then get left up to human vision, judgment and yes at times unconscious bias. The Chiefs play in a lot of really big games so those human flaws get magnified.
A lot of folks have talked about how the NFL needs to use technology to solve for the spotting of the ball, "chip the ball" they say. And I 100% agree, but I also realize it isn't just "chipping the ball". Spotting the ball in many situations is at a minimum a two-variable issue. One variable is where the ball is. The other variable is where is every part of the ball carrier's body with the exception of his hands in relation to the ground (ie when was he down). In other situations where he doesn't go down, it's when was the whistle blown and where was the ball (forward progress stopped) In some situations video/audio makes that easy. Synch up the video/audio to the chip in the ball. I think they should be looking at this with all expediency. That said there are still going to be those times (think piles of bodies around the goal line, etc) where the video isn't going to help there so that system also won't be perfect. That doesn't mean they shouldn't be working on it.
