umm just looking real quick, but Sullivan? N Perez? Both are W powered, which is something you absolutely dont want in Coors, Perez is a bit overpriced when both your MI are max 3 game injuries.
Your pitchign is medocre at best, I don't think you will score enough for that kind of pitching to work. CC has to many Bp hr's, and your pen is 2 R1's, with BP hr's (albeit not many). I could see using Helling, Crain, J Rincon, M Gonzalez, and for god sakes, Jenks is out there! Remember all pitchers will do worse in Coors, but really you need you rp's to bridge at least 3-4 innings every game. Yours cannot do that as of now.
R Tejeda and Kazmir are better choices for your 2 sp's IMO.
