I get this, totally. I have serious doubts we add a solid SP'er to the mix, but I see it this way: even if Gio takes Pivetta's job and does it well, AND they decide to put and keep Whitlock in the pen, are we really oaky with just running back the same rotation, next year?
Aren't we just begging for the same results? Another near-miss.
Houck, Gio, Crawford, Bello still leaves the 5th slot open, as Criswell was never intended to be a 28 start pitcher. Sure, they might think between Criswell, Fitts, Priester, Dobbins and (gasp) Whitlock, we don't need one, but do. I am certain of this.
I see our chances being very slim at doing anything great, next season with a status quo rotation, and I feel the same about the pen. I don't see adding Hendriks, Whitlock & Fulmer as being an upgrade over Jansen and Martin.
I'm not predicting major additions: I am suggesting (and begging for) them.
