From what I saw, the 3d line didn't give a decision (like GLT). Its just a line you can superimpose on the screen. I am pretty sure a lot is still left to the operator, what camera feed to use, which frame, etc. I could be wrong though.Seeing that they have the cool new 3D line technology to view offside position decisions fairly instantly, I'm sure that the time to "check" this goal would have taken almost exactly the same amount of time in either case.
Precisely my point. Was it a big enough one, it would have taken more time.Perhaps it wasn't a big enough decision?
