If they don't add a pitcher or 2 either through FA or trade, essentially, they will be fielding the same staff that has been failing miserably since September 2011 except that Lackey will be taking Beckett's spot and Bailey will be taking Papelbon's spot. Also, I think it is overly optimistic to think that Bard can return to what he was prior to 2012. He has all the signs of a shot pitcher. His command is completely gone and his velocity is way down.
IMO if we don't add pitching, we will lose 90+ games in 2013. I could see them. Having an even worse year. Our number 1 problem is our starting pitching. I realize that the FA crop is thin, but many posters believed that we should abstain from the 2012 FA market, because they expected this year's FA pool to have a bumper crop of top line pitchers including Cain and Hamels. They and other top pitchers extended with their current teams. Hoping that better pitching will be available next year or the year after carries no guarantee. The market is thin, but it is better than anything we have not named Lester and Buchholz, and Lester is a big question mark.
