I like Criddle's show too. The podcast feature has made it easy to listen to a BYU sports show while out of state for the first time that I can think of. It isn't perfect, but honestly, I don't know how you center a show on BYU athletics and make it interesting and palatable to all year-round. His guest lineup is terrific.
I don't know how much windshield time people have in Utah, but I would think that a 3-hour show/podcast would suffice for many, if not most.
No need to launch a liberal political-PAC-style boycott, IMO, of the ScottyG's of the world. If guys like him are what people here say he is, just don't tune in. He'll either have to go full on yewt and compete with the other shows that openly cater to that audience, or eventually go away.
Also, whether they admit it or not, I suspect most radio and T.V. pundits that cover BYU are on here a lot, if not regularly, if not all the time.
