Explain how college and pro football games are linked?

I'm pretty interested in the linking functionality of the college and pro games and I'm trying to figure out what exactly it will show you. Can anybody answer these questions?
I know you still have to manually import the draft classes and this isn't automatic.
there is a button for linked news on the league homepage but it shows nothing. What news is it supposed to show and what do I have to do for that to happen? I've already linked the two leagues together.
What's the best way for me to play the college and football game in order to get the most out of this? Do they have to be synchronous? In other words do I have to play the 2022 college season and then stop once the draft class is generated and then play the pro game so i can see the college news or can I sim multiple years of the college game and save the draft classes and then play the pro game at my pace? Will the college news in the pro game still work if I do that?
