Most of those guys have very good pure stuff with a couple question marks, like command (Feliz), innings jump (Sale), or home park (Pomeranz). I like Luebke the most out of that group because for H2H you can play the @SD game. For this year only, I would say:
Reasons: Luebke has strong peripherals and the most favorable home park in the majors. Sale probably has the best pure stuff of the group. I have a good feeling about Samardzija so this is mostly just a gut call; the NL Central isn't scaring anyone this year though. Feliz might actually have better pure stuff than Sale but walks might be a problem with him and Arlington is a tough place to pitch. McCarthy doesn't excite me but his home park will help him enough. I'm not sure I see a big difference between him and, say, Jason Vargas. Pomeranz might not get enough innings to make a big impact this year but he's one of the highest-upside young lefties around. Pitching at Coors and not having a very well developed change (he's fastball/curve almost exclusively) I expect him to have his ups and downs, but he's a name to remember. His upside is Kershaw-esque. Someone to target in 2013 for sure. Alvarez has never hit 7 K/9 anywhere in his minors career, let alone the majors. I'm not seeing the upside, especially in the AL East. He's not going to pitch 200 innings, he's not going to strike many guys out, and playing against TB, BOS and NYY so much I can't imagine his ratios being all that stellar either.
