I have vivid memories of 2008's playoffs. They ran into a buzz-saw in Tampa Bay. Here are some names from that playoff pitching staff -- Garza, good-Kazmir, David Price, James Shields, Grant Balfour, Edwin Jackson. They also had the magic of Johnny Gomes, and their lineup still had Crawford, Pena and a healthy Longoria at the time. The reality was the Red Sox couldn't get runs on the board, and while Varitek didn't hit much, no one did. Lester got a total of 2 runs in support over two of his games, and that was the real difference.
Fred, listen to yourself here. Depth is never a bad thing. Good teams have good depth. Bad teams have no depth. Look at 2010 and 2011 as prime examples. 2013 was a team that had amazing depth, and look what happened. People on the board here made the same exact argument about Drew last year... the Red Sox didn't need him. Well, he opened up Iggy for a trade and got the last key piece for the WS run. The Red Sox's bullpen depth seemed a bit too deep, maybe they shouldn't have signed that Koji Uehara guy.
You're going to give UN? an ulcer if you keep arguing on this because trying to make the case that depth is bad is silly.
