Listening to Joe Root doing an interview on sky he would like to see county cricket matches last four days. Maybe he says award more points for draws so batsman can learn to play with scoreboard pressure not being a distraction, although this might be more boring for spectators to watch he argues. At the same time pitches should deteriorate as the game goes on to bring the spinning option more viable in county cricket.
For me if we need to learn how to play spin, then apart from producing wickets that will turn. Then it should be compulsory for counties to pick at least two spinners per side and they must have a minimum quota of overs each.
