Do you think the cubs rotation is doing well?

Including Zambrano today, thats 4 straight quality starts. Ted Lilly, Marquis, Hill, did great. Zambrano went 7 innings and 3 runs, and that was the worst start, yet it was very good. I also think Zambrano can do better. I didn't think their rotation would be this good, but its still very early. Its also good to see Lee and Ramirez smacking the ball everywhere.
