So here's a question: what law of the game stops the attacking team have a couple of players lift one of their colleagues in the air at a corner, like in a rugby lineout, in order to get higher than the defence? I'm sure this can't be allowed, but what stops it? It'd be quite fun to watch, and to see how a defence tries to combat it.

Sure but in rugby they are pretty static when they do the lift. Even having the height advantage, with a static target you would need the corner to be incredibly accurate to hit the man. The header would then have no momentum to generate any power on the header, as well as having to direct the header.

Its a nice idea, but even if legal, i dont see how it works. 

Not directly mentioned in the laws of the game, but would probably fall under unsporting conduct.

Sure, it would be a bit tricky to get right, but at worst you miss the man and get a far-post delivery and at best, a free header on the six-yard line.

But is it legal?

That would be a stretch wouldn't it? Start going down that path and you end up banning those somersault throw-ins, starburst freekick routines, what next?

Go on Bens - do it. I won't charge a penny. ;)

Really reliant on an inch perfect corner. Otherwise you have 3 players out of the game. How would The lifted player gain any momentum to put any pace on the ball.

Seems you're right though. Boo.  :no:

Use a Segway?

The 'Unsporting behaviour' rule is nicely vague to capture anything that might fall just outside the 'laws of the game', like piggy-backs.
