The thing is, the show is targetted at skaters, and after like 5 or 6 years of doing it, they've run out of interesting skate guests who want to come on. I'm sure they'd love to get Rickk Howard, Mariano, Koston (which would likely be great episodes given the history, almost all the Girl/Chocolate related interviews are great), but its clear those guys have passed and likely multiple times. The other thing they are hurt by is they want to do in person, which I get. So anyone outside that SoCal bubble they have to hope they eventually come. I'd be curious if Rog could get some old school Boston heads such as Gangemi, Panama Dan, and Jahmal.
The show is far from perfect, and has obvious flaws (way too marketer friendly in questions/positive, not very well researched unless they have a history with the guest etc.), but I do think they are really suffering from the fact they've essentially interviewed every major skater in SoCal (who can easily be there in person) who wants to go on.
