I think that was the plan in a non-covid world where we'd get neutral match-ups in London, Mexico City, States with no NFL but strong college followings, St. Louis, San Diego, San Antonio and the like. Texans Vs Cowboys at Kyle Field for the lone star bragging rights.
I think my biggest concern here is the players. 16 games already takes quite the physical toll. I know the idea is to reduce preseason, but they barely play starters in preseason. Preseason spreads the risk a bit, but more regular seasons games is going to be way more concentrated on the starting players.
