I'll answer this for you. Both pitchers you guys picked up are good pitchers. Anderson has ace-like stuff. McCarthy is a solid middle of the rotation arm. Problem is, neither of these guys stay healthy. McCarthy hasnt pitched a full season since 2011. Anderson has pitched a full season once in his career (his rookie year of 2009).
If these guys stay healthy, your rotation is going to be ridiculous. But I wouldnt count on more than 30 starts combined from these two.
