I would also like to know this! Commenting to come back later :)
Vader offers the NFL games in their video on demand library a couple of days after the games are live.
Vader had all the games up in Matchcenter catchup late last night. The earlier they were on the sooner they get posted ect ect. ESPN and a majority of their other channels (guessing there might be some super random channels that might not have it that I've never noticed) are usually up for catchup an hour or so after they air.
As i've pointed out in the past once you weed past the mountain of misinformation, and the random fanboy or tech noobie feedback here, it's really a highlight feature that no other provider claiming to be the "best" is bringing to the table. Huge feather in the cap for Vader there imo, and a big comparative issue I have anytime i try somebody else. Kodi doesn't always cover everything in a timely manner, and once you get used to the catchup option being there it's hard to go backwards with that surrounding expectation.
Only downside, other then the standard "doesn't work 100% of the time" IPTV concern, is that fast forwarding can sometimes bug the playback out. So if it's a 3 hour game you are kinda stuck watching all 3 hours with commercials, or constantly running the risk that your attempt to skip ahead 5 minutes actually skips ahead to some random point far ahead. For whatever reason, the last couple UFC PPV catchups in particular were hit or miss on being posted up as well which used to never be the case (the Jones fight wasn't posted, the McGregor/Mayweather fight was solid live, but buggy as crap in catchup, ect).
Not trying to hijack, but something similar for sportscenter would also be nice.

It's $35 a season. I've used it for the past 3 seasons. It's amazing. They get a direct feed of NFL Gamepass. You can watch all the live games. You can go back and watch the games afterward. They even have condensed versions without commercials.
