This is a bloody good point. In those 9000 games, how many GLT decisions were made? How many of them were non-obvious (i.e. back of the net bulging etc.)? How many of them were close line-calls? How many of them were goal-mouth scrambles with, say, more than 4 players on the line? And so on. Once you start removing those items from the "9000 List" the odds of Hawk-Eye fucking up starts looking far less favourable.
People need to stop banging on about the "overhead view" that Hawk-Eye didn't supply or Sky didn't show. That image isn't from a camera. It's CGI - special effects. It's a rendered image from the mathematical model they use to work out if the ball has crossed the line. If the system has lost the ball, for whatever reason, at the wrong moment, then this data won't be available and the render can't be produced.
Similarly, people need to not carry on talking about the Sky cameras picking it up and such. The Sky cameras did, clearly, which is why everyone in the entire worl knows it went over the line, including Hawk-Eye, Michael Oliver, Paul Teirney, the PGMOL, the EPL, UEFA and IFAB. Noone is saying the ball didn't cross the line. The footage was available to VAR who didn't review it. That has no bearing on Hawk-Eye, which uses dedicated, and very very different, cameras from the broadcast-spec ones Sky use.
Also, think about where the Hawk-Eye cameras are. It's not just people on the goal line that could block the view. I still find it bizarre that this is the first ever time that at least 6 of the 7 cameras had their view totally blocked at exactly the wrong second, but I can at least conceive that it is believable such an arrangement COULD occur. But lets face it, the ball was behind the line for more than just a split-second so it wasn't exactly momentary as Nyland was looking sheepish for at least 3 seconds as he got up off his arse, so how come the cameras didn't momentarily lose the ball and then pick it up again clearly over the line? THAT is the question we should be asking!
I mentioned to a friend of mine that, given the outcomes, i bet the EPL are glad that the Black Lives Matter protests etc. all happened. All the players taking the knee mean that focus will be on that show of support, so the EPL can keep quiet and hide behind that until this shitstorm blows over. Of course, as a result of that, i then got accused of equating the importance of #BLM to not being awarded a goal in a footy match and got the typical virtue-signalling lecture i've come to expect if you don't immediately throw yourself on the sword for such movements... but my point still stands. World events like #BLM enable the EPL to focus on the positive message of footballs support for an important equality movement, and all the while use it as a screen for the fact the Laws are in a state and the governing bodies are so incompetent they couldn't find their respective arses with both hands...
