Papelbon pitched a full season every season. He was very reliable, and often outstanding. While saves is not the best way to evaluate a pitcher, Papelbon did reach 200 career saves faster than any pitcher in history. He'd been through the pressure cooker of Boston and triumphed. Before we crown Bailey to be as good as or a tick below, let him prove it on the field. As of now, he hasn't thrown a single pitch for the Sox.
Like him? I don't even know him. I don't like or dislike FO guys. I look at their record. This guy has done little to nothing so far in his tenure. You haven't proved otherwise. Even if I conceded all of your points, which I do not, he still has a completely undistinguished record.
