To me there is no card in the world even close to being worth $67,000.
Even for Mayweather vs Pacquiao the most I would have paid for ring side seats would be £1000 ($1337). Might have paid slightly more for stacked Pride cards back in the day.
If I didn’t get the UFC legally for free in the UK I wouldn’t even have paid $10 to watch 306 let alone $67,000 for a third row ticket.
