I am not criticizing Rio, because he's a kid and I don't expect much from him...
I don't think he caused chaos, I think he put in a decent little effort at lw but is also positionally all over the place. I don't think hes ready. He needs games elsewhere. We shouldnt be reliant on him in any way and we need better than what we have as a starter.
Rio gets seen as a solution for the same reason chiesa does ,because we would just rather see something different.
