There was an attack at the beginning of the Bunley Bournmouth match where the attacker looked to me to be offside. The linesman* didn't flag and I imagine that was on purpose because if the attacker scores then it goes to VAR anyway and is checked. If he flags, the ref blows and play stops but he was wrong, then he's stopped a possible scoring opportunity when it would be checked anyway, so why would he do that?
The attacker shot but it was saved, the ball rebounded into play and play went on. So here's my problem with it - if play goes on and it ultimately results in a goal, let's say after enough time and moves that this initial shot is not considered to be part of the same phase as the goal, then that means a goal is scored by the attacking side after an offside decision was deliberately not given because a goal would be checked by VAR, though ultimately it isn't.
So what does the linesman* do? Flag, risk being wrong when everyone will say wait for VAR, or don't flag but, well, what's the point in being there if you don't? Or should VAR always go all the way back to a possible offside no matter how long ago? Which would completely change the game. Or, should he flag if he thinks it's offside, the ref holds off blowing his whistle until the phase is finished and if a goal isn't scored he gives the offside? Which is complicated, difficult for the ref and means players have to completely ignore the lino's flag from now on. Is that what we were told after our play-to-the-whistle moment?
