Well, the number of credible #2 starters just decreased by one, as the San Francisco Giants just signed Randy Johnson to a one-year deal. Financials not available.
If you're keeping track, that gives the G-men three Cy Young winners in their starting rotation. That's crazy.
That also leaves only John Smoltz as a pitcher I would be OK with (maybe) as a #1/#2 starter. That's crazy too.
