Hafner worth the pick up?? Who can i drop? WHIR!

[BiGAnT]

I need some help with RBIs (and even HRs) BUT my lowest category is ERA and WHIP (I had Lackey, dropped him today)...any advice on whether or not to add Hafner and/or someone like Marlon Byrd who is playing really well right now?? I'm hesitant to drop SP since I need to gain so much ground in ERA, so I'm thinkin maybe League or Chapman, but at the same time those guys are usually a cheap source of ERA, Ks and WHIP (and League is the closer over there too)

Anyway, here's my team, let me know what you guys would do
Also, I'm in a 12 team mixed league and am in 8th place

C Geovany Soto
1B Ryan howard
2B Brandon Phillips
3B Casey McGehee
SS Jimmy Rollins
OF Alex Rios
OF Chris Young
OF Vladimir Guererro
Util Ben Francisco
BN Maicier Izturis

SP Roy Halladay
SP Chris Carpenter
SP Ryan Dempster
RP Jordan Walden
RP Sean Burnett
P Tim Hudson
P Carl Pavano
P Zach Britton
P Chris Narveson
P Carlos Zambrano
P Aroldis Chapman
P Brandon League

Thanks guys!!

Drop Chapman. I did it to get B. Morrow in my H2H league.

Chapman's control is still all over the place. I don't think he'll be taking over Cordero, @ least not this year.

The way Hafner is hitting in that lineup, I wouldn't be surprised to see him return to form.

Only thing with that is, someone actually wanted me to include him in a trade that he was trying to make with me, so I feel like he has some value, and that people would want him simply for ERA and K's...but I do see him as one of my only droppable players so I gotta decide, or else I'm worried Hafner will be gone...also, what are your opinions on Marlon Byrd? Pick him up over Hafner, or no?

Thanks!
