It's not that easy.
If there were three owners in the Western US who were the least bit interested in the AFL, the AFL would have found them.
The AFL is a damaged product. So is indoor football, in general. There aren't that many owners who are willing to risk what the AFL is going to require.
So simply being able to build more teams and place them into a division to save the Titanic is like the other ships on that fateful night they just won't get there in time. everybody on this message board has ideas but implementing those into a real action is quite different than simply writing an opinion.
The AFL has hit the wall as far as scaling goes so now its agenda for at least a few season's should be on a continued branding and building up just what arena football really is a niche sport, for a specific audience while it may not be your grandfathers game it could be the great grandson's, but they don't appear to understand that.

Portland will fold because the other team owners are already throwing money down a hole trying to keep them operating with nothing in return. These guys aren't NFL owners printing their own money (and think back to when there were NFL owners in the league). What makes anyone think they want to throw more money down 2-4 other holes?
"We were going to do this one set of things, but then we saw a message board post from some random guy obsessed with team names and we thought, 'What have we been doing all this time?'"
