I think they should scale it way back. Let the game be called as is, and give each team a “coach’s challenge” and you only get one. Keep the goal line tech on the watch for the ref, but after that, fouls in the box, offside, no offside, hand balls, etc etc.. let it all be subject to the ref and lines men and when there is a particular important moment where a manger feels they are in the wrong, let them throw a red flag and and do the VAR check. You only get one a game so it better count for your side.
