Fa Trial sin bins as grass roots level

Found this on BBC sport FA to trial sin bins for desent at grass root level can only see this as a good thing for football it works in other sports cant see why it wouldn't work in football
Personally if its a success I don't think it will be to long before we see at the pro level would certainly change a lot of results
