I Need Help!!

Fevvers

Vital Reserves Team
I'm probably showing my age but more importantly my lack of footballing knowledge, but I'll ask this question anyway.
Have just watched (replay) the Wolves v Leicester match. I'm stunned at the no goal decision! I guess "all" of you guys have seen this.
I'm under the impression that ; when taking a corner kick, the ball is coming direct from the "dead ball line" and therefore the first receiver cannot be off-side, he's behind the ball ??
Help me.....
