Yellow card = Sin bin
And/or allow retrospective punishments for items that were punished by the referee during the game.
Right now it's something like:-
Dive during the game and get spotted by the ref = yellow card and no chance of further punishment
Dive during the game and it is missed by the ref but picked up retrospectively = red card and 2 game ban
The current discrepancy means players will still chance it during the game.
Set the clock to 45 mins per half and stop it when time wasting or other stuff happens
30 minutes per half is the proposed plan by the FA, that's about how long the ball is in play in a typical game. Would certainly be worth a trial in some matches to check for unintended consequences (I can see some teams with lower fitness using tactics to give their players more time to recover).
Shirts should come apart if tugged too much.
A great opportunity for time wasting and conning the referee by tugging ones own shirt (no innuendo intended).
