It'd be hard to find a better fit for this team than Rizzo, if the price is as low as Dalbec.
And it wouldn't surprise me if Henry and Werner are enamored of the idea.
I doubt it. He actually pitched pretty well for 5 innings last time out. If AC had hauled him after 5 it would have been one of your mini-quality starts with 5 IP and 1 ER.
Now see here, Dean of Old School, if someone says they think ERA+ is a good stat, that means they take ERA seriously as a stat. And the adjustments that are made are common sense adjustments.
