This should be called the Ennis rule. He was famous for throwing the ball at players, tripping over with hands outstreched plowing his sizeable chin into the ground.
Glad you picked up on this. One of many sneaky tricks up his arsenal, he was the best at running into offside players and using them as a shield into he defensive line as well.
I thought it was great gamesmanship from him. Probably says something about how shit of a job the refs have when I can actively applaud a player for stretching the rules.
