Would you also like the refs to be checking whether all players named to play front row are actually trained to play in that position?
How much time would you like the ref to have with teams in the pre-match talk? I'd have thought the teams would prefer minimal time with ref interruptions.
While we're at it, maybe we need to implement the Player Movement Sheet (as you see in finals and rep games) in every fixture and make it incumbent upon each team to have a manager who brings the sheet to the referee when ever there is a player substitution.
