What to do about Liriano & my pitching staff...

[twinkypoop]

12 team 5x5 cat Roto league, and my team stinks so far.

I asked a question about adding Chris Davis earlier, and I wanted to follow up with a question about my pitching rotation as well, specifically, who should I drop at this point to start playing the FA pool for my SP's.

My Pitchers are as follows:
SP: Liriano, F Hernandez, Lilly, Danks, G Floyd, Josh Johnson, Scott Richmond
RP: Nathan, Wood

& the rest of the roster:
C: Navarro
1B: Berkman
2B: A Cabrera
SS: Hairston
3B: Branyan
OF: Braun, Bay, Rios, Ethier, Abreau, Cuddyer
BN: Iannetta
DL: A Ramirez

My RP's have been ok, Wood hasn't had many opportunities, and Nathan is his consistent self.

In terms of my starters, Lilly, Johnson & Richmond have been pretty consistent, Felix has had some Ace like performances, but also some stinkers along the way, and Liriano & the two Chi-Sox starters have been HORRIBLE... (although Floyd and Danks finally had decent performances last week...)

I have been patient with my staff so far, and I have a hard time giving up on SP's like Liriano, but any advice whether to be a little more patient or who are droppable at this point would be great!

Thanks for your help!!
