Sorry, it took me a while to reply.
I'm not an insider to that station or their group, so all I can do is speculate. What I can say is many of the small market stations aren't paying someone to update a webpage anymore, because mainly there's no revenue attributed to it. Let alone for a station that carries syndicated national programming 24/7. That could be the same reason they aren't bothering to link through their ineffective webpage directly to ESPN because they get nothing from hosting such a link.
Were I an owner of such a station, I'd keep my site and preserve the URL... mostly so I could use it for station email accounts and the like.
But then I'd have a series of links to my social media station and talent accounts. Like the afternoon drive host? Here is their Facebook or whatever account where you can follow them and make comments as you listen.
Otherwise, there is no reason why anyone would want to go to a radio station website... ever.
In Europe, some of the big national stations have good sites where the feature links to derivative formats that are online only and have quick links to their local traffic, weather and news pages. They also feature "how to" links to get your phone to install their traffic, news and weather apps.
Some of my favorite French and Italian "stations" have 15 to 20 different music options, often with music from decades they no longer cover, or just hits in something other than their local language (a French favorite has several formats of just English language or Italian hits).
The website is like a junction in the road... it just helps you find the feature of the station you want. My favorite is
https://www.nostalgie.fr and I can click "radios" and get a big selection of formats I really like. Try the "mur de radios" (radio wall) full of optional station derivatives; 48 different formats. (I'm addicted to the French oldies from the 60's through the 80's myself)
