But seriously, football would be better without it. It's a feature that barely requires any skill, just to have good genes. It would promote real footballing skills. And it would be fun if it would get banned now Rags paid 80m for Maguire. Van Diyk would be half of what he is too. We would barely be touched, we're team of midgets anyway.
There already is a version of football with no heading - futsal. From an attacking point of view, heading does require skill (timing, getting it accurate from a cross whipped in, glancing header, diving header, etc), and you don't need good genes or to be a giant. Aguero and Messi are both good headers of the ball, most of Cahill's goals were headers, Owen, etc.
No skill involved here...
