The Clay & Buck show is awful. I gave them a chance... listened to them a few months when they first started. They suck. Clay definitely doesn't sound like the brightest bulb in the box. He says the same time over and over again.
The guy who should have taken over Rush's show is Rob Carson, who used to write Rush's comedy material.
He in in Rush's slot in the Baltimore area. He is tolerable, but the juvenile comedy for three hours gets tiresome fast. I end up tuning out. Rush was incomparable.
