It doesn't matter as much as losing someone like Hill would make many believe.
Everything is relative FFS
I mean no one is saying that losing Hill actually makes them better, in isolation. If losing Hill contributes to making them more balanced, allocating that money to other parts of the team rather than tying it all up in a WR, perhaps a better running game, etc, etc, then yes, it could actually make them better. But strictly put, you don't just replace a WR like Hill. You reallocate. And Mahomes is still there, which let's face it, it's a QB league and the QB matters more than anything
