Welcome to SB Nation Reacts, a survey of fans across MLB. Each week, we send out questions to the most plugged-in Chicago Cubs fans, and fans across the country. Sign up here to join Reacts.We have discussed MLB expansion here fairly often https://www.ccfanstore.com/Jake_Arrieta_Jersey-131 , most recently a couple of weeks ago.There have been a number of reports about expansion; some seem to indicate MLB might want expansion soon, to pocket big-money expansion fees for current owners, but others, as I noted in the linked article above, say it could be closer to the end of this decade before MLB adds two teams.Further, according to the most recent SB Nation Reacts survey Ron Cey Jersey , a slight majority of fans don’t think the league should add any new teams. Six potential locations across North America have been mentioned as leading candidates for future expansion: Nashville, Charlotte and Portland in the United States, plus Montreal and Vancouver in Canada. There have also been hints MLB might be interested in placing a team in Monterrey, Mexico at some time in the future.In the most recent SB Nation Reacts survey, fans were asked to rank those cities in order of preference. Nashville took the top spot, followed by Montreal, which was previously home to the Expos. Anthony Rizzo Jersey The next question MLB would need to answer is how many teams should be added. Most likely, two teams would be the optimal choice since the last MLB realignment, in 2013, organized teams into divisions with an equal number of teams for the first time since before the leagues split into three divisions. Having two 16-team leagues, which could be divided into four divisions of four each, would seem to be optimal.
