I just listened to this episode a second time, and found it pretty informative. No, he doesn’t have “one neat trick to fix knee pain,” but I like his first-principles approach: figure out what positions and movements your sport requires, and then work to make sure you can get into those positions and execute those movements. I also appreciated the principle that your work off the bike should support your bike-related goals, but this doesn’t mean it should mimic your movement on the bike (in fact, it probably shouldn’t). Yeah, his delivery may not be your cup of tea (it’s not mine), but I have found his videos and books helpful in developing my own ability to figure out how to move better. Teach a man to fish … etc.
Also found the podcast informative with the takeaways you listed. Big fan of Coach Chad deep dives, and while a completely different style I also enjoyed watching Kelly Starrett on the YouTube podcast.
Bought Deskbound, Standing Up to a Sitting World and its a great book, like an owners manual for anyone working at a desk. Last night on a group ride I recommended it to an accountant with back problems.
Man it’s sad to see people be so negative for a free video on trying to help people feel better 
If it doesn’t work for you so be it but man don’t hate on Kelley or the TR crew.
I tried the free trial on his website. It seemed like he just used a bunch of big words to try and sound smart but didn’t really show you anything you can’t find very easily on YouTube for free. The website was also very clunky.
I have learned a lot of good stuff from his Instagram though.
