Sp free agent/fa help

[Kratos86]

Here are my pitchers:
Cole hamels
Justin verlander
Ervin Santana
Kyle drabek
Matt Cain
Justin masterson
Zach britton
Rick nolasco

There are some good free agents that I would like to add such as:
Derek Lowe
Michael Pineda
Brandon morrow
Matt Harrison
Aaron harring
Jordan Zimmerman

Should I add any of these guys? If so who is the odd man or men out? Thanks

Drop Santana/Drabek. Pick up Pineda/Morrow. I'm a sucker for high K/9, though. What are your scoring categories?

[Kratos86]

Too late for pineda, he just got picked up. It's inning pitched, wins, ks, era, and whip

Morrow/Zimmerman over Masterson/Ervin
