Ellsbury got injured and missed most of the season. Lester has been healthy. His game has been slipping for the last 2 years.
I don't think either of them are that good. I don't think they are part of the short or long term solution. These are bottom of the rotation guys at best. They don't project any higher down the road. Most likely, Morales cannot hold up physically over the course of a season as a starter. Even if he can, he's just a bottom of the rotation guy. He's already 26 years old with no track record as an MLB starter. I'm not getting my hopes up.
