definitely needed. a yellow card does not aid the team the offense is against, so 10 minutes in the sin bin as well as the yellow card would be a more just punishment. waving an imaginary card should result in the offending hand being chopped off as well. i find this action a most disgusting lack of respect for opposition players and the game.
Not a good idea for me, especially not for persistent fouling. The game has got less and less physical as it is, and if you ask me a free-kick should be punishment enough.
I'd vote for it probably, but I'm not sure it would have the desired effect. A more important introduction for me, as a few people here have suggested, would be some kind of rule that only the captain can question decisions, approach the referee etc. I think the big problems are a) players do everything they can to cheat b) lack of respect for the officials. I don't think a sin bin directly addresses these problems. I'd also worry about anything that detracted from the simplicity of football and the current system is simple (if often applied controversially).
I think this is what irritates me the most, being honest enough to stay on your feet if you can should not prevent you from getting a penalty. If players knew they'd still get the penalty, they wouldn't bother going down, and you might get more chances in open play.
Without the assistance of video referees I don't think this will be effective. Eg. Bale in spurs last game in the epl, should hey play 10 mins without there best player purely because the ref assumed he dived? Multi million pound decisions rest on the shoulders of referees who need assistance, yet its not given. Video referees would clear a lot of inconsistentcies up. And probably take less time than it takes for most teams celebrating a goal
That was my point though - even when he was touched and therefore technically fouled, he elaborately fell to the ground.so yes, I think they should be without him for ten minutes. Would stop him cocking around.
