Heard stat that Brentford, on promotion, are now the 50th team to play in the Premier League.
Quite an amazing stat really, almost 30 seasons, 50 teams rotating through a 20 team league.
Of my generation. I can think of a few 1980s First Division teams from that decade that haven't played Premier League yet; Oxford, Luton, Wimbledon, Millwall, Swindon.
I think some of it is that some of the yo-yo teams have to go so far out on a limb to get promoted, that if they come straight back down they can plummet even right out of the 2nd tier as well for a few years. Opening up space for the next challengers.
But, 10 to 15 years ago. If you'd told me a team like Blackpool , a quaint team of yesteryear, Stanley Mathews, maximum wages etc etc, would make the Premier League ... I would have scoffed.
