it's so very simple. you pay a $ fee to espn+/SEC+ and if you have a TV provider like YOUTUBE.TV then you can access it. it's that simple.
No. ESPN+ and SECN+ are two entirely different ways to access.
To access SECN+ you need a providers such as YouTubeTV or spectrum or whatever that includes the SEC network as a channel.
To access the ESPN+ feed you pay $9.99 a month
Both feeds exist on the ESPN app.
You do not need to have both.
Despite both ending in + they are entirely different in the way you access the feeds, which show the exact same game.
