All of this was headline editors not knowing how commissioners work.
#1 - it was the World Series "State of the League" address, not like, a new development to talk about.
#2 - he's clearly saying whatever he can say to get Oakland to approve. The whole thing reeks of the Penguins and Kansas City. Everyone knew the teams belongs there, and needs to stay there, but politician need to make it happen, and politicians don't act proactively, they react. Manfred is saying whatever he can to get the Oakland shovel in the ground.
#3 - Manfred has been jonsing for expansion before the pandemic wiped away billions in revenue that expansion fees can replace. He needs Oakland or Tampa to make a stadium deal for "musical chairs" purposes before he can expand. If he tries to expand before OAK/TB have stadiums, there's 2 teams and 1 city to steal them, so no one HAS to build anything. If OAK or TB get a stadium, he has 4 cities for 3 teams and MLB can force city's hands.
Much ado about nothing.
