I said it in another Oakland thread, because we were talking about how there kinda NEEDS to be two teams in the Bay Area because that market is so huge..
When you don't look at MSAs or CSAs, but really who's in the accessible region... A 70-mile radius around Oakland has about 14 million people in it (SF, SJ, SAC, Stockton, Modesto, Napa, Sonoma, Santa Cruz, etc).
But the same 70-mile radius around the northern suburbs of Chicago has about 12m people in it... and Milwaukee, which is a THIRD MLB TEAM.
One franchise moved to Milwaukee and then left for greener financial pastures in Atlanta.
The Brewers exist because Kansas City threatened baseball over the A's moving and the AL expanded hastily to KC and SEA, but Seattle just wasn't ready yet so Bud Selig bought the Pilots franchise for Milwaukee.
The Brewers are an incredibly charming franchise, with an old logo on par with the Hartford Whalers, so no one wants them to move. But they've also been an incredibly "small-market, poor" franchise that has success via really smart executives (Who they usually can't keep. Stearns is probably taking over the Mets in December).
Of course, it sucks for anyone to lose their team, but the reality is that the Chicagoland-Milwaukee corridor should have TWO teams, not three; and the Bay Area should have two and not one.
