Question about starting rotation last year

[Priorknowledge]

Does anybody know the combined ERA of the Cubs' starting rotation last year including young guys like Marmol and O'Malley over the course of the entire season?

 

Also, does anybody know where I can find a breakdown of performances by rotation spot?

 

Thanks much.

Wow-looking at those stats makes me feel a lot better about the rotation this year. I mean-3 people with 9 starts or more that had ERA's over 7. 3 more people with 24, 13, and 10 starts with ERA's in the mid 5's. While the rotation still has question marks, it should at least be a lot better than that.
