HELP ASAP for 2 Moves Please

[gotham]

I've got two decisions I need some help with please.

1. Victorino off DL, I need to plug him back in the line-up. I was able to replace him with some decent talent. Who do I drop to bring Shane back in? Ludwick? Here's my options....

OF Ibanez, Raul(OF) PHI
OF Joyce, Matt(OF) TB
OF Kemp, Matt(OF) LA
OF Ludwick, Ryan(OF) SD
OF Morrison, Logan(OF) FLA
OF Quentin, Carlos(OF) CHW
U Aybar, Erick(SS) ANA
U Cabrera, Asdrubal(SS) CLE

2. Feel like I need to dump Ryan Dempster... his ERA is killing me, but his K's are abundant. Do I drop him for better ERA? I'm 7/10 in K's catagory, 6/10 in ERA, and 5/10 in WHIP (mixed Roto 5x5.) Here are my available options...

SP Blackburn, Nick(SP) MIN
SP Collmenter, Josh(SP) ARI
SP Crow, Aaron(RP,SP) KC
SP Gee, Dillon(SP) NYM
SP Morton, Charlie(SP) PIT
SP Porcello, Rick(SP) DET
SP Zimmermann, Jordan(SP) WAS
RP Harrison, Matt(RP,SP) TEX
RP Humber, Philip(RP,SP) CHW
RP Stauffer, Tim(RP,SP) SD
RP Vogelsong, Ryan(RP,SP) SF

Thanks in advance.

1) I would drop Ibanez (or Ludwick)

2) Drop Dempster. The wind starts blowing out at Wrigley around this time of year, so his ERA is gonna get even higher. Of course, his xFIP is quite low, so his ERA should be lower. Still, in a 10 team you can do much better than Dempster.

I was thinking the same route on either Ibanez or Ludwick, but Logan Morrison has been on the downhill the last couple of weeks.

[khabibul35]

Logan is young and has a much higher ceiling than those 2 guys. Don't give up on him.

I do understand, but a non-keeper league... play for now, right? Mentally, it's tough to drop either one while they are producing. Thanks.
