The only 2 guys the Braves have nearly a lock to be real MLB contributors (2+ WAR for many years) are Lango and Harris, and now Lango is gone. It is absolutely critical that Harris pans out, and at least one of the pitchers need to figure out how to be effective for 180+ innings a year.
What we are seeing now is the prototypical closing of a window of contention. We saw it with the Cubs and Nationals very recently. All the cheap talent gets more and more expensive to replace, and there isn’t enough talent in the pipes to fill in the gaps.
I think the Braves have solid WS chances until Fried either moves on or blows out, at which point we will see how good/great of a GM AA truly is. Good GMs can build a winner. Great GMs can transition between contention windows without extended rebuilds. The Astros, Rays, Dodgers and As are the model franchises at doing this.
