Not denying that there are a lot of positives from this series: Lester, Morales, Gonzo, Pedey..and so forth. CB will get better, and Beckett will get better IF he is not hurt, as I suspect he is.
As you said, the pen is a problem. I don't know how you can really compete for the playoffs with a pen that is as bad as ours is. Also, Bard and Doubront are unknown entities as SP. They could excel; they could stink. It will be interesting to see how they do in TO.
