Depends if you think you can contend next year. I'd rather have Halladay than both of those guys for 2013 and 2014. 2015 is where it starts to get dicey, and can you project pitching out three years?
Pineda will take at least a year to come back from the injury (this assumes that the true Pineda is the 1st half of the year 2011 and not the second half 2011).
Hultzen is a nice pitcher, but everything I have heard about him is quality, not incredible upside.
