This isn't based on any facts. But my take on these guys is Lieber can be a stable back of the rotation guy, with no real upside. Marquis may give you a few more excellent games, but also more disaster starts. I could see going after Lieber with the hopes that he won't be a disaster. Maybe not great, but not horrible. The only thing is, he's way past TJS days, and coming off foot surgery. You can't really hope he'll be any better than he's been the past couple years, and he might be worse.
