The sports talk radio in Salt Lake I still listen to had a baseball guy on from USA Today. He pretty much guaranteed the A's are out of Oakland and will likely land in Vegas (unless that has issues and Salt Lake can steal it).
Said he's heard about Portland, but thinks the Mariners would be against it because they are close enough people there will travel up to attend games in Seattle.
In the East, he said erryone wants to be in Nashville. Also said there's interest in Montreal to get a second team in Canada. But with the stated desire to have one team in the east and one in the west means both can't happen unless Tampa gets moved to Nashville.
Gail Miller (wife of former Jazz owner) is behind the expansion push in Salt Lake. She's pretty smart, so I wouldn't think she'd be wasting money. I'm guessing she knows something. And it's smart to get on the board early. I don't know if Salt Lake will get a team, but the next few years with Tampa and Oakland getting worked out and then figuring the expansion teams. Will be interesting to watch unfold.
