That chiefs play

The formation the Chiefs used was weird. Toney (who was called offsides) has the purple arrow. And yes, he's lined up beyond the ball. 

But he's not the only issue. The center (blue) is further up than the rest of the offensive line (yellow circle) which is also an illegal formation. 

And the receiver at the top (yellow arrow) is in the backfield based on where the ball is spotted. Meaning the center in this case is the only guy on the line so he's technically an eligible receiver, which he is not. Also illegal. 

And then Taylor swifts bff is at the bottom with the green arrow. It's an illegal formation to have a player in the backfield farther out than the last receiver. 

So chiefs fans, players, and coaches can cry all they want. The play may have been genius in possibly scoring the winning TD.  But the setup was a mess. And the refs were correct.
