Clear opportunity for more casts about sports.

Both professional and recreational. 

Have been doing a bunch of user research recenlty and it’s the clear number one most popular non-ceypto category where people read / watch content on other social networks.

I onboarded a friend, he is a soccer fan. But since he is new he doesn't have followers and doesn't get engament in his posts.
What would you advice to do different?
I have a bunch of friends who love sports but they would be casting to the void because as a new user is hard to get just a couple of likes
