Hader, Boxberger, and Gott inspire a lot confidence. Suter has been a solid reliever the last three years. Williams has been a top 5 reliever in baseball the last two years. Do they need to find some more reliable relievers in the back-end of the bullpen? Yes. But that can be done a heck of a lot easier than things like finding aces in the rotation or an all star-caliber shortstop, which we thankfully already have.
You say that we shouldn't have taken too much from beating up on the Pirates and Reds. Well, by that same token, why should we make grand conclusions about this team from one bad series against the Reds? Even good teams have bad series against bad teams. Look at the Dodgers, who just lost 2/3 to the Pirates...Last year's 95 win season and this year's fast start to the season tell me most of what I need to know about this team.
