I really enjoy listening to John Clayton from ESPN. He lives locally here in Seattle. The guy is so smart and has a memory like no one else. Plus his grasp of facts and data about the NFL is best in the business. He comes on the local Sportsradio station (KIRO 710 ESPN) every weekday at 4pm for 20 mins. It's the one time of the day that I actually go out of my way to listen to. Here is the podcast link for it:

He also has a call-in show every Saturday morning from 9-noon.
Obviously a lot of the content is centered around the Seahawks, but as anyone knows about John Clayton he has knowledge about all of the NFL.
Sorry sports radio folks in Utah - this is what sports radio is supposed to be like.
