Likely because the league/owners get revenue sharing from all the additional Euro sponsorships and broadcast rights along with the same U.S. dollars?I can hear someone at the league say they want to grow the sport. But the owners want to grow their own wallets. They compete for the right to host the SB because they can make a ton of money even if their team isn't playing in the game. Why would they hand that money and prestige to someone in London?
