It's way too early to draw any conclusions, but...
Trevor Hoffman has gotten hit hard 3 out of his 4 appearances so far this year, and absolutely hammered in his last two. The Brewers don't have the starting pitching to handle an imploding closer.
Chris Carpenter has gotten hit hard in his two appearances this year. Franklin has been hit hard so far this year too, as has the rest of the bullpen. Their defense has been suspect so far.
We saw just Cubs and their pen and defense.
The Astros and Pirates are the Astros and the Pirates.
The Reds definitely have a lot of problems, mainly their offense, but I think they clearly are not in much worse shape than anyone else in the division.
Basically, it looks like it will be pretty ugly this summer in the NL Central.
