I posted this elsewhere, but it's probably better suited to be in this discussion. NFL Films annually releases two different Blu-ray/DVD sets for the Super Bowl winners. The first is titled "Super Bowl Champions <Roman Numerals of Super Bowl>: <Year> <Winning Team>" and releases in early March. This release contains quick summaries of each game, with the playoff games getting a little more runtime, and the Super Bowl naturally getting the biggest chunk. It includes sideline and locker room footage, interviews, media day and some pieces on the most relevant storylines surrounding the team's season. I believe this is a 1-Disc release.
The second is titled "<Winning Team>: Road to <Roman Numerals of Super Bowl>" and releases in early June. This has always been a multi-disc release and contains trimmed down versions of the initial broadcast of 4 games (all 4 playoff games if the team played 4, otherwise the 3 + 1 of the more memorable regular season games) with no commercials or between play analysis. There are little to no special features on this release except a trivia track.
Oh, and they're probably a lot cheaper anywhere else than the NFL Pro Shop.
