On last night's penalty decision and VAR.
It was a penalty if he was onside so it's this part that has been the most contentious with Chelsea producing their own evidence taken from their own camera high on the gantry, and not the host broadcaster's.
For me he possibly was offside but on the evidence the VAR official had to go on, it was impossible to judge the upper body, the best he could do was really look at the feet. Kane did get the benefit but the VAR official (Scholfield apparently) did do a decent job with the angle he had available to him.
It only took 93 seconds which isn't excessive on so marginal a decision, possibly it could be speeded up but i don't think that's too bad at all tbh.
Apparently they can only use the host broadcaster's feed and therefore wouldn't have had access to Chelsea's feed from a camera on their gantry, so you can't blame the VAR official for that.
My thought is while VAR will get some wrong due to the shortcomings of the available evidence as of now when it's introduced, it will hopefully improve further with familiarity and future technological advancements, but even as it is now, the percentage of incorrect calls will absolutely be far lower and only the very marginal perhaps liable to be called incorrectly.
It will cut out the real howlers and there is a compromise to be made with speed of decision and even more accuracy.
93 seconds can seem a long time and the amount of decisions as close as last night will be a relatively small percentage. If you look from every angle there are two things to consider, firstly they are limited to the host broadcaster's feed and can't use angles derived from other cameras as Chelsea's was last night, and even if the broadcaster had other angles to show there is no guarantee that they would be accurate enough either.
It would inevitably slow the process anyway but that may be ok if the technology was there to give an angle directly in line. As the offside line could in theory occur anywhere within an opponents half I don't think you'll ever get a definite answer to every call, giving the striker any benefit may just have to be accepted.
