I just tried to set something up recently and ran into the problem of RSS feeds with low subscribers not being maintained. I wasn’t able to get articles from any of the local sites

I also recently fired up the old RSS reader (to fill the void left by Reddit until I found Lemmy). The main feed I was using was the Yahoo! Sports CFB feed:

https://sports.yahoo.com/college-football/rss/

The only issue is it's a fire hose of content because it merges all the articles from different teams' beat writers (and sometimes random HS football coverage creeps in, too). I try to follow the whole sport, so that's okay with me, but if you're mostly a fan of one team I would look for just that feed.

I only just added 247Sports' feed to my reader, but it seems to be really promising so far:

https://247sports.com/Page/College-Sports-News-and-Recruiting-100021//Headlines.rss

I think both sites have feeds for other sports, too.

I have FreshRSS running on the website I've had for eleventybillion years and finally found something to do with it when I (mostly) left Reddit. Here are the feeds I have:

• Star Wars News Net. They could be crap, I don't know, but in the end who cares? I'm a grown man who pays attention to a Disney-owned media franchise. Self-respect went out the window in favor of nostalgia a LONG time ago.
• XKCD
• NPR News
• Local DFW TV station that hasn't killed their feed yet
• BBC Science and Environment
• Verge
• Keyboard builders digest. Oh man, I'm super excited about the plates I have coming from Xometry for a TKL design I tweaked on keyboard layout editor and pairing them with some DSA keycaps. Going for a whole "vaguely reminiscent of various 8- and 16-bit computers" vibe. I hope they aren't too rough to finish decently.
• FC Dallas feed
• Jacksonville Jaguars feed
• NFL, soccer, and NCAAF feeds from CBS and Fox Sports
• Sports feed from a Jacksonville station that is shamelessly leveraging their AP stories
• "ESPN Dallas" feed
