Knapp is also my favorite and, in all honesty, I only listen to shows in which he hosts anymore (unless the Punnett or Noory guest just happens to be spectacular).
However, much of the reason I like Knapp is that each of his shows he is impeccably prepared. And it's not just from his lifetime of field research. You can tell he's put the preceding 1-2 weeks into methodical preparation of backgrounders, questions, etc., unlike Noory who seems like he gets a pile of 4x6 cards shoved in front of his face by Tommy 10 seconds before airtime.
Knapp's guests are also, and always, cream of the crop. There's no numbers ladies or John Titor or what have you.
And so, I've often wondered, would I still like Knapp as much if he did the show nightly, which would (1) eliminate a lot of his prep time, and, (2) necessitate he lower his standards in terms of guest quality to fill 10x the number of shows?
For me personally, instead of seeing George Knapp be the nightly host of Coast to Coast AM, I would be happy to settle for just 2x as much Knapp. I'd like Knapp to have an every-Sunday show entirely separate from C2CAM and then have C2CAM just quietly fade into black.
