Bad cops, Bad cops, wat'cha gonna do? Wha'cha gonna do when they come for you
on their suped up crotch rockets.
I feel like it's super easy for anime and manga to do this since it's full of different types of otakus and manga especially lets them output what they like a lot.
I think it has more to do with anime not being limited to a specific setting or demographic. For example, if you tried to make a unique show about Boxing in America, they'd have to find some way to make it fit the procedural/drama formula.
Anime has its own formulas. But it doesn't always stick to them. Hajime no Ippo is clearly a Sports/Shounen. But that doesn't mean it imitated Dragon Ball/Naruto.
