guys, who should i pick in the 1st round of my prospect draft? .. its a 20 team H2H in its 2nd year, so alot of good players were taken last year.  i've narrowed it down to these 3

Zach Duke
Chris Nelson
Brian Dopirak

i'm leaning towards Duke because its hard to get good young pitching and i think he's ace who'll be ready the quickest.. but Nelson seems too good to pass up and Dopirak seems a 40 hr type.. any thoughts? please help
