Hurley is the clear #1 out of that group. Check out this John Sickles Bailey/Hurley smackdown.
For people who missed out on Bailey, Hughes, Garza and other nice young sp's, take Hurley. Many are staying away becasue he's in Texas but that's BS.

I rate them as even in background/intangibles. It is extremely close with physicality/tools, with Bailey having (perhaps) a slight advantage. Hurley has better current performance and polish. Bailey has an edge in upside, though Hurley's is still respectable. Overall, it looks like Bailey comes out a bit ahead, but it's very close, and both of these guys have a good chance to be successful (granted all the usual caveats about young pitchers).
