"We were as bad as any team when he didn't. We now have one...count 'em...one proven, healthy, major league starter. That's Niese. He's a good pitcher, but no #1. We are going to be awful for the next 7 years."
But this is a pretty harsh and pessimistic view of the rotation. We did rank 11th in the majors in starter ERA so it wasn't just Dickey. Niese was good, Santana was good for half the year, Harvey was great, and Gee is about average. There are certainly question marks with all of them but it's not TOO big a stretch to say the rotation could still be above average or even good.
As far as the future, if Wheeler and Harvey are what we expect, we absolutely won't be awful for the next seven years. Again, they may very well not be but it's not as if the potential isn't there.
