We're at the point where shares on Youtube, TikTok, IG, & Twitter are more important than traditional ratings because nobody's doing anything numbers wise and haven't since 2016. If I go on ESPN's Youtube rn I wouldn't be able to find one clip from a whole 30 minute episode of PTI, I'm 100% sure FT will be there multiple times over.
FT I'm sure without question is the most viewed show on their morning block, so if it carries the morning programming and is the most virally shared content on their social pages, I don't see how you can call it anything but the flagship.
But I see your view when you give thoughts on Max saying he's a sunken cost, if it were Skip would you still say it's an upgrade? Because that's the difference, at that point you take the radio spot because your next spot is Fox Sports if you don't. If that Skip/SAS/Jay Crawford formula was there with Max sending him to radio wouldn't even be an option. Add in that the two highest paid personalities in the company at one point both did FT and neither were Mike & Mike and yeah it's a downgrade.
