In 2003 to 2005, the Red Sox had record setting offensive production. It might have been a surprise in 2003, but it wasn't in the subsequent years. The Sox clearly had the superior offenses during 2004-05 without the benefit of hindsight. In 2004, the FO also picked up one of the premier starters in the game-- Schilling to head the rotation with Pedro and Lowe. They also added one of the premier closers in Foulke.
In 2007, the Sox added the most sought after pitcher of the off season to head a rotation with Beckett and Schilling (who did pitch a 1 hitter in 2007, before getting injured). Dice K wasn't just some import. They also added Drew whose talent has never been questioned. In 2004 and 2007, the FO made bold moves to improve those teams to compete with and beat the Yankees. The 2007 team went wire to wire. They didn't get there because of the emergence of Ellsbury late in the season. They were built to win, and they won with underperformances by Lugo and Drew that were balanced out by the unexpected emergence of Pedroia and Okajima. They were built to win. It was not a case of that team getting lucky.
This year they made the big pitching acquisition, but they have clearly taken a step back offensively dropping further behind a Yankee team that had already become dominant offensively thanks to the addition of Mark Teixeira. This year's team is not built to win. Kotchman and Cameron are not going to get it done.
