The Sox had not won a World Series since 1918(!), and hadn't appeared in one since 1986. The offer was made in 2002. They made him an offer, thinking that he would lead them to a Win after an 84-year drought. Despite his refusal, they were still able to win 3 championships.
Maybe this shows that while Beane can get you wins, his method may not work in building a Championship-winning team?
Beane turned down the offer, but Theo Epstein (then Sox GM) employed many of Beane's tactics. I suspect the reason he found more success than Beane is because the Red Sox have a payroll over three times larger than that of the A's.
And of course, Big Papi's 8 walk off hits in the 04 playoffs, and the pitching in 08 and 13, certainly did not hurt.
Perhaps. In 2002, the Red Sox hired Bill James, who formulated the sabermetrics that Beane popularized. The GM they chose after Beane turned them down, Theo Epstein, is also considered a practitioner of sabermetrics.
Since you like football, let me bring up Marty Schottenheimer. Most regular season wins since 1966, but no Superbowl appearances. Goes to show, you can do well in the regular season, but the playoffs are a different beast.
