Regarding the screenshot I couldn’t stop it on the release of the ball as it didn’t show conclusively that the ball had been played. The screenshot I posted shows the ball has moved so Madden must have been onside at the split second the ball was hit for the linesman to look at the ball hit and then the time it then took for him to look at Madden, probably showed him offside with his speed of movement. Unfortunately Madden was onside at the split second the ball was played but not when the lineman looked. Conclusion to the linesman OFFSIDE.
