Larger than three games I would guess.
Here is the first response I got from one of the Sawxheads historians. Admittedly, it contains a lot of assumptions. I do believe the part about Lucchino not giving Epstein free hand in the Schilling signing because Epstein was still so new on the job-just like Cherington is being used as a marionette by LL now:
First thing you have to remember is that in 2003 when the Sox brass went to Schilling's house at Thanksgiving--Theo, despite the GM title, was still Larry's apprentice, with Larry still having total veto power over anything Theo wanted to do. So that's a huge point that's been forgotten in folklore.
Here's the main points:
1. Schilling and D'Backs owner Jerry Colangelo became very close during his stay in AZ. They won the WSC in 2001. In 2003 Colangelo decided to unload some contracts and asked Curt if he'd be willing to waive his no-trade. Curt told him two teams only--Yankees or Phillies. That went public with Curt publicly laughing off any Sox possibility, calling the Sox "A piece of ****, loser organization."
2. Colangelo began talks with Steinbrenner and the Yankees. Now, mind you, a year or so previous to that Colangelo had reached a handshake agreement with David Wells to pitch for the D'Backs, only to have Steinbrenner swoop in and take him away at the last minute. So there was bad blood between the two, but they initially tried to civilly reach an agreement for Schilling to head to NY (which was Curt's preference at that point). The Sox made overtures, but were told "No way," by Curt and Colangelo. Things quickly went sour again between Colangelo and Steinbrenner, becoming increasingly nasty to the point where Colangelo refused to deal Curt to NY. Not only did he cut off talks, he now wanted revenge.
3. Colangelo appealed to Curt, as a friend, to help him exact the ultimate revenge against Steinbrenner by considering Boston. There were unconfirmed reports that Colangelo paid Curt off to change his mind, but whether or not that's true it was only a matter of days until Curt acquiesced, agreed to at least listen to the Sox brass and allowed the Sox contingency to his home on Thanksgiving. Henry, Werner and Larry and Theo all went. Henry and Werner left Larry and Theo behind after a day and two days later Larry announced they had the deal done. The Sox had Curt and Colangelo had his revenge by trading Curt to Steinbrenner's hated rival. A few days later Curt was in Boston spewing, "I hate the Yankees. The Yankees suck." Go figure.
4. It's also important to remember that, at the time of the announcement, Larry was deeply committed to building up Theo's credibility after having taken some criticism for handing Theo the job at such a young age---so Larry, in essence, gave birth to all this Theo folklore by embellishing Theo's role in the Schilling trade. Larry really kind of purposely took a back seat and had Theo take the bows. That's how a lot of this crap got started.
In the end, Pumps---whether it was really Theo or Larry or Henry or whoever who people claim engineered the Curt deal is inconsequential. It's all moot. At least that's what I found when I researched it very thoroughly back in the day. The whole deal, and the Sox involvement, was conceived and consummated, not out of any mastery, sheer determination or professional artistry by the Sox brass, but due to Colangelo being consumed by hatred for Steinbrenner and being willing to take as little as a bag of balls in return if it meant he could screw Big George all the way with the red hot poker--which he did. This was purely payback, with both Schilling and the Sox being nothing more than pawns in a rich guys' ongoing spat. The Sox were merely the right team, in the right division, at the right time. Nothing more, nothing less. They could have sent Trot Nixon down to Schilling's with a six pack and the result would have in all probability been the same.
The rest of course is history, with Theo's role becoming increasingly embellished by the year. My guess is that the truth really won't come out until Larry writes his book at some point after he retires.
That's the basic summary. I hope this helps. PM me if you have any more Qs.
