TV Pundits - Stop guessing!

Just imagine when the driving instructor fails you after your driving test for going the wrong way down a one-way street. Would he change his mind if you argued, "but the law's not clear about whether you can drive the wrong way down a one-way street." No, of course he wouldn't.
And likewise it would be a really good idea if the Match of the Day pundits bothered to spend £3 buying a copy of the Laws of the Game and checking Page 24, where the offside law is presented on one page, concisely written.
The fuss has emegred because of Birmingham's habit of placing a player in an offside position at free kicks, between the player taking the kick and the goalkeeper. Both times I've seen the move, a five man wall has also been between the taker, the goalkeeper and the player in the offside position.
He is not interfering with play. He is also not gainig an advantage by being in his position because that deals specifically with rebounding balls. The only element that applies is "interfering with an opponent." Is the player "preventing an opponent (i..e the goalkeeper) from playing the ball by clearly obstructing the opponent's line of vision."?
If he was one yard from the goalkeeper with no-one else between him and the shooter, maybe this would be the case. But in Birmingham's case there's an entire defensive wall blocking the goalkeeper's line of vision, so the player in an offside position is not blocking anything from his position 10 yards away from the keeper.
So, the player is NOT offside and it strikes me that Birmingham's players and staff have been a little cleverer than most in reading up on the Laws of the Game. Good on them. Perhaps Messers Lawrenson and Linekere might dream of doing the same thing.
