The last time around the rotation, Ryan Vogelsong, Matt Cain, Madison Bumgarner, Tim Lincecum and Barry Zito were hammered for 34 runs in 232/3 innings. That raised the vaunted group's season ERA to 4.87, which ranks ahead of only the Brewers among NL teams. Vogelsong is the biggest question mark. He just can't figure himself out.
