I understand completely. It's something that has happened to both rugby and football. Where once anyone could just go to a game and take the family for a couple of quid and go to every game if they wanted to, it is now too expensive. These days it's saving up for an annual trip. £60 is 2 days works disposable income for most people , it's mad. We used to get the coach down form Builth for the day, I only went on Sunday because a/ I live in Cardiff and b/ I got an almost reasonably priced restricted views ticket.
A league of only 6 teams, with a 1 in 6 chance of finishing in the relegation spot every season, would have a massive impact on games, teams would change how they play to avoid finishing last. TMOs would take hours as they become million pound decisions. In Football you have 3 spots out of 24 teams (1 in 8) which isn't that far off 1 in 6, but it's over 46 matches which means one yellow card decision doesn't make such a difference. The drop between the 1st and 2nd division is huge, but not as massive as between Tier 1 and 2 in rugby
Italy are not a bad team, if the current team was playing in the 6 nations 10 years ago, they would be title contenders and they are part of the 6 nations family now. Expanding to 7 nations would extend the international season too much.
