I get what you're saying RE minors. But wanted to point out that baseball can't expand by just one, like the NHL, NBA and NFL can. They HAVE to expand by two teams at a time.
The motive behind Manfred's pro-expansion agenda is ease of scheduling. It's difficult to match up the right teams to play the one interleague series always going on in MLB, because there's 15 teams in each league. With 32 teams, it's so much easier.
He didn't just mention Vegas: "Portland, Las Vegas, Charlotte, Nashville in the United States, certainly Montreal, maybe Vancouver, in Canada."
The Montreal Expos are in a situation similar to Quebec. MLB is more than willing to welcome them with open arms... but they need a partner. It’s an open secret Montreal is team #31.
Nashville is interesting. They’d be the ideal choice from a “how do we align this thing? standpoint, because they can slot in based on what everyone wants very easily into either league’s Central, East or South.
Oh, I know, Kev, but just pointing out that even a 1-team expansion would require, in truth, more than that as baseball's minor league system is deeper than the NHL's. As for the rest of Manfred's list:
Portland - Needs a park, currently in the design phase of one. Lost their Triple-A team in 2010 when their park was converted to being a soccer-only facility. Market is currently served by the Short Season-A Hillsboro Hops. Since they're not a full season team they could relocate somewhere else in teh Northwest League's footprint (WA, OR, ID, BC) or simply go dark.
Las Vegas - As mentioned earlier - building a new stadium
Charlotte - Would need a new park as the 4-year old BB&T Ballpark is too small to be an MLB facility (10,200 seats) and can't be converted into one. Home of the Triple-A Charlotte Knights - Knights would have to relocate to another city in the International League's footprint
Nashville - I'm not sure if the 3-year old First Tennessee Park can be converted or not. Home of the Triple-A Nashville Sounds- Sounds would have to relocate to another city in the Pacific Coast League's footprint
Montreal, I'm sure has been well discussed - they'd need a new park but there'd be no MiLB ramifications other than an expansion
Vancouver - Needs a park. Formerly a Triple-A market but they lost the Triple-A Canadians to Sacramento, CA. Currently home of the Short Season-A Vancouver Canadians. Since they're not a full season team, they could relocate somewhere else in the Northwest League footprint (WA, OR, ID, BC) or simply go dark.
