There has been a lot of talk lately about video refs should/shouldn't be able to rule of blatant forward passes. The same goes for knock-ons you see every week in the game. If you can't tell a forward pass because of camera angles than surely the same rule applies to everything bar put downs/ obstructions ect. It got me thinking. Does anyone here know much about Hawk-eye? It works in tennis, its been used in cricket for many years and it's about to be used in the Premier league to tell whether the ball has passed into the goal or not. I was wondering if anyone knew enough about it to tell whether there has been a forward pass/ knock on and to what degree? It seems kind of technical i know but most here have spats after being on the end of a bad call and I gotta say benefit of the doubt seems to be going to the team the video ref likes the most. Could Hawk-eye be leagues answer for the video ref shambles?
