Well, he asked what WBUF could flip to. If there are no music format holes in the market, which there don't seem to be, then the point is maybe a talk format is all that's left, especially when the competition would be stuck on AM.
If not political talk, where your points are well taken, what about sports, hoping to pull the audience away from WGN (AM)?
92.9 has a good, full market signal, doesn't it? But the most attractive music formats are already covered by either heritage stations in the market or by Townsquare's own stations. All that's left is a niche music format like soft AC. Or Hispanic, but it looks like Buffalo' demographics are only 5% Hispanic.
