Not convinced this would happen, tbh. Not in todays over-complicated strategic world of football. I could be wrong, though, just think they should try it out, maybe in the non-league in England, would liven up my trips to the Park.
I think what really annoys me is them piss-arsing about with it constantly, trying to lessen it's impact. first-phase, second-phase, level onside (I mean when is a human-being ever exactly level with another).
Having said all this this, they could just properly ****ing implement the rule they already have tried to, "benefit of the doubt should go to the attackers". If they'd only had the balls to back that up, and when a linesman had giving an attacker onside, and he was yards off, just say "fair enough, benefit of doubt was giving the right way", we'd of stopped all defences playing a high line, or all the other pernicious ways of dull unimaginative, crappy defending, which is just meant to destroy any creativity.
Oh dear, possibly my longest ever post on Cricketweb. It's something I feel quite strongly about, tbh.
Probably years of watching lower league ****e football, where the lino constantly takes the easy way out, and flags for everything against the attacking side, no goal, no big controversy, after all
