Not near enough value for Halladay. One of the Roto Arcade guys did a quick analysis on Morrow and basically found that this year against bad teams, he's great, but against good teams (like the rest of the AL East), he was pretty bad. He will get you K's, but at the cost of your ratios.
As for Sale, this is a pitcher who had tenderness in the elbow earlier this year and is starting for the first time in his career. Those are red flags right there, and this is coming from a Sale owner. You can get much more for Halladay.
