What's Porcello Worth?

[jazzmanljg]

The minor league roster on the keeper league team I took over this year is a little weak. I took J. Heyward with my first pick because I really needed a bat more then an arm. However, Porcello is still on the board, but knowing the guys in the league I don't think he'll make it more then another 5 picks. I was thinking of offering one of my current ML pitchers to a team in need in return for their draft pick so I could take him. I just have no idea what is fair ML value for a top (but unproven) prospect. These are a few of the pitchers I have to offer:

M. Mussina
G. Meche
T. Gorzelanny
C. Sampson

Picks aren't worth that much.
