He must have given 2 interviews then because in the one I saw he said he accepted the decision but didn't like the way the flow of the game was interrupted.
I think that the issue of the a 2 minute delay is what bothers most fans. It reduces your connection to the game. You have to emotionally detach yourself from goals when they go in, and wait.
There are issues such as scope for manipulation and the precision with which they can make an offside call. I think they should change the offside rule because I don't believe they can do what they claim, i.e. measure absolutely whether a player is offside or not.
