Seriously? Papelbon is as good as Foulke ever was. He had 1 good year with the Sox, that's it. 2008 Papelbon had a 2.34 ERA and 41 saves, 2009 had 1.85 ERA and 38 saves. So according to you, the "transition" Papelbon managed to have a ridiculous year, better than Foulke, but it's all gloom and doom for the future?
Papelbon Career: 1.85 ERA, 154 saves, 4.22 SO/BB
Postseason: 1.00 ERA, 7 saves, 2.88 SO/BB in 7 series.
Sure his walks have been a little worrying, but the guy is still one of the top closers in the game.
