Avila wasn't good at his job and earned his way out of town, but I do think some combination of relatively successful drafts at the end of his tenure and the changes he made in player development deserve recognition. His personal role in the draft aside (as Eddie has said, PBOs aren't that involved), it shouldn't be that controversial to take the full view.
I also think a lot about what the national press said about this job right after he was fired.... I recall RJ Anderson from CBS Sports basically said it was a **** job and that this org would struggle to find anyone decent to take it, and I suspect a lot of folks in the baseball world probably agreed. Yet they ended up landing Scott Harris (who wasn't even on most peoples radar and who had been sought after by other orgs), who apparently saw a canvas that he felt he could build off of.
Harris deserves a lot of credit as well, he's obviously added additional new personnel (ie. Mark Connor, Rob Metzler) to the org as well.... but it shouldn't be hard to use a little nuance looking at the situation.
