I know the difference between Tampa and St Petersburg hence I live in Florida and I know the layout of each city. Its no big deal.
In all seriousness and in real life I gotta wonder where would two new teams come from for the BIGs??? From what I heard Portland was a solid choice but MLB has stated a few years back they don't want to infringe on minor league attendance. They also Suggested San Antonio as well. MLB even toyed one year with the thought of having a team in Las Vegas. However they turned that down when the local minor league team renovated their new park.
I would love to see 2 new teams come to the forefront. It will be interesting to say the least as to what happens and who they choose IF any.
