I think its because of the Super Bowl and Favre making hay with Rison in the lineup. And Tanier explicitly says when its a run of a team with basically the same characters, he picks one representative sample so they can discuss more teams.
But the 1995 offense, league ranks aside, the better unit. Football Outsiders had them over 20% DVOA that year, in 1996 they were 15.2%
Everyone talks about Favre and Holmgren, but the D reached better performance (though they had a big letdown in '95).
