It depends on what you are looking for. If it's straight wins, Lidle is a good pick, because he gets excellent offensive support. However, his ERA is at like 4.90, so that can be a bit of a drain. If you want ERA and K help, have a look at Ischii. He gets lots of K's and keeps his ERA down(and pitches in a pitchers park), but also walks way too many batters, so he will drain your WHIP. Kinney and Johnson have respectable K, ERA and WHIP numbers, but play for bad teams that have lousy bullpens and lousy offensive support, meaning that you can't expect many wins. Webb has still only had like 3 major league starts, so I'm not sold on him, and when all the DBacks' starters are back, he's the odd man out and will have to go back to AAA. Using rookie pitchers in fantasy leagues is a risk I always like to let other owners take.
