Honestly it's really difficult to pick any of these pitchers. They are all pretty awesome and they all have their own downsides.
Strasburg and Sale - Dr Andrews haunts both of them in the future
Bumgarner - everyone's safe pick throws sliders 36% of the time - he's still the safest but some claim that sliders destroy elbows
Harvey - he's a Met and he's pretty awesome so something tragic has to happen.
Miller - He is almost exclusively a 2 pitch pitcher throwing his FB 75% of the time
Moore - effectively wild but those control problems could prevent him from ever moving into the 1st tier of starters
Fernandez - has an impressive fastball but he didn't really make anyone look foolish with his secondary pitches (during one game that he was awesome). I NEED TO SEE MORE OF HIM!
I'm happy though because I have 3 pitchers on this list in a 24 tm league in addition to the 'New Derek Holland' and hopefully the 'Old Matt Garza'.
I picked Harvey.
