I do think the farm is more bottom level heavy, but I don't think we are all that weak at the top. Here is a look at what the farm has given us, recently and the ETAs on those to come:
We have no graduated prospects prior to May 2021 on our roster, except Devers (SEP '17.

In this light, the talent seems pretty evenly distributed.
