I've seen one game at Goodison, sad as that is, and it rocked. It was back in the day when there was that semi circle behind the goals (I bet Tim wishes it was still there!). Anyway, as much as I was only a little bloke at the time, it made an impression.
Here in Oz, the AFL clubs were mostly suburban and had quaint old grounds like Goodison. My Dad used to collect discarded beer cans and build a little platform for me to stand on. There were open areas, standing areas, and many dodgy food outlets that specialised in Salmonella. But those were from days long past. They were the products of an evolving sports organisation. Eventually, the game got bigger than the suburban grounds & dodgy food. It became a corporate juggernaut and is the 'premier' sport in Oz. Being able to command billions in TV rights and professional players & administrators, the powers that be decided that the sport had to evolve. As a result, there are no more matches at suburban grounds anymore. All games played in Melbourne are at the MCG (95,000 seater) or Etihad Stadium, a purpose built indoor stadium (55,000 seater).
Now, I'm not comparing Apples with Apples here, obviously, I'm also not talking ground share either, but the PL has evolved into a massive organisation and that attracts big corporate dollars. At some point, History will not be enough to get a top investor or a new player into our club.
What is one of the most common themes with new signings? Ambition. What is one of the key indicators of ambition? Investment. Everton needs to invest in its future and whilst expanding Goodison would be fine, if it can be done without causing grief to the local residents, a new ground would be the smoothest way of doing it.
