Sweet mother of god NO!
DO NOT drop Liriano for Litsch.
I watch a lot of Jays games, and Litsch is a run of the mill 5th pitcher who has no place on any fantasy teams active roster. Liriano may be sucking right now, but his upside is 3467 times better then Litsch.
Drabek is actually a very good pitcher... but he is young, inexperienced, and needs to learn to hit his spots. He is much better than Litsch, but like Liriano, will have up and down times. For THIS year, I'd prefer Liriano, but Drabek is very promising in the near future as well.
If you really need to pick up someone from that list, I'd probably go with Dempster... but I wouldnt drop Liriano to do it, and even Drabek would be a risk (personally I wouldnt do that either). If its a keeper league, I certainly wouldn't drop either Liriano or Drabek for any of those guys you listed.
help with mine?
