Beehaw is an instance that doesn't allow you to create your own communities. They want a smaller amount of communities that are more active rather than a large amount of smaller, less active communities.

Other instances let you create communities, but that's why I'm on Beehaw. It's a bit more curated and I feel cuts out a lot of noise I don't need.

So yeah, I'd say just use the Sports community if you want to stick with Beehaw but if this instance isn't meshing with you there's no harm in making one in say, Divisions by Zero for example. They allow you to make communities and are federated with Beehaw so people here could still interact.
