I still have DTV so am covered with games on FS1 and FS2, although if there were storms, I'd be screwed since Fox isn't putting any games on their app. Meanwhile, the first two days were set with feed commentary. Then Fox was up to their old tricks putting the US guys on games again. I guess with Strong and Holden, they need to put these guys to work but I assume they're paying Donny Baarns and Cobi Jones to freelance. Why? Just use the feed.
Here's a rule of thumb: if the game is on FS2, they go with the world feed, if it's on FS1 they use their own announcers.
You'd think they could use the SAP, but they still haven't figured that trick out in 20+ years of it being an option.
There's been plenty of times when other channels/outlets have been used for alternate presentations (with different announcers), but you'd think it wouldn't be *that* hard or expensive to use SAP for world feed announcers.
If they're paying for their own announcers, why would they want to pay a penny more to provide another audio feed in the same language with somebody that's not their announcer? This isn't the MNF ManningCast where the network hires well-known personalities to try to attract an audience with an alternate production--it's an anonymous British guy on the world feed.
