A fifth starter is rarely if ever needed in the postseason and a fourth won’t be needed in the division round if things go really well. A staff of 12 or possibly even 11 should do the trick. Choose the four best starters (Gray, Lopez, Ryan, and probably a rested Ober) and then choose the best remaining 7 or 8 to round out the staff. Simple, but that doesn’t mean the decision is necessarily easy.
