Gee thanks lol
The "committee" was largely Chad Fox, who got all the save chances. Fox was an ok reliever who had some bad games in Boston, but was largely the fall guy for an ineffective bullpen. He did go on to get a World Series ring with Florida that year.
The rest of the bullpen struggled. During the 54 games before Byung-Yun Kim was acquired, Fox blew only three 9th inning leads, resulting in two losses. The real struggles for that pen were in the sixth through eighth innings, normally not the role for a closer. That the Sox struggled where the game was really on the line in earlier innings was the exact logic for using a committee. The problem wasn't a lack of defined roles as they had those. The problem was too many ineffective pitchers handling key situations.
The true best pitcher from that committee turned out to be Timlin, but he didn't emerge as a force until the post-season, where he was unhittable. Of the committee pitchers, it was no surprise he was the only one the Sox kept re-signing...
