No matter how times this hayride passes by, it's hard for me not to jump on.

As this sentiment has been posted by many others as well, I have to take issue with it (although I fully support your awesome screen name).
I think they fail massively on two counts:
For those who are new to the sport, P&P provide and incredibly narrow view of both the participants
and the race events (could that be considered a "laser-like focus"?). The new viewer is unlikely to be made aware of
any rider whose strong performance doesn't fit the prearranged narrative. If that same rider happens to be named, say, Henao, then getting P&P to admit that a place called South America evens exists will be prove to be quite the challenge.
The deluded transparency that they exhibit when fawning over the ToC and other "grand tours" is beyond embarrassing. Their paid bias is insulting to the intelligence of anyone with half a functioning brain cell still operating. To them, the peloton is made up of about 20 riders and the season consists of only half as many events. It does a disservice to the viewer and to the sport itself.
I can't think of any other sport on U.S. TV where the personal bias of the commentator wouldn't be called out in a very public way. Of course cycling gets zero coverage outside of the P&P, and the vastly superior Todd Gogulski and Steve Schlanger presentations, so that will never happen. If ESPN had a talk show similar to any of the others that recap the week in baseball, basketball, or whatever, that was geared towards cycling with people that actually understood the sport, then P&P would get shredded. Have you ever seen the FOX Sunday Football crew throw barbs at each other? Of course! They call BS on one another at the drop of a hat. The infomercial style of P&P would be rightfully torn to pieces. But that will never happen — they get away with it
because cycling is off the radar. There's no one there to keep them in check. If the sports section of the New York Times won't do it, then the likes of Velonews sure as hell won't either.
On the other side of the fence: One of the things I respect about Todd Gogulski the most is
not the fact that he raced on teams with both Greg Lemond and Lance Armstrong, it's the fact the
he never mentions it. He knows the sport, he loves the sport, and that's apparent in his broadcast style.
As far as either Harmon or Kirby: I only get them in small doses but they don't really bother me. I always find their enthusiasm for the sport entertaining and I can figure out the details of the race on my own. Plus, it's very cool to have translations of any post-race interview regardless of the language being spoken (I forget which of the two is fluent in at least five of them).
P&P, however, became a joke such a long time ago that it is no longer funny.
