NESN's DVD of the 2007 Red Sox World Series championship season, "Champions Again: The Story of the 2007 Red Sox," will be released one week from today, on December 14. NESN also put out a retrospective of the 2004 championship season called "Faith Rewarded" which was a terrific DVD.
This DVD is available through NESN's web site, and also at retail outlets throughout New England. I doubt I'll find it here in New York City, so I'll have to mail away for it.
Here's some more info on the DVD:
