The Tampa Bay Buccaneers apparently had the single most productive draft class of the 1994-1999 seasons. In 1997, the players they drafted combined to play 1,175 games and start 772 over their careers, according to Scott Kacsmar of Football Outsiders. He looked at every draft class in the NFL over that period, and the Bucs did so well in that single year that there's a bigger difference between them and the second-place 1999 Denver Broncos class, than between that Broncos group and the 1998 Eagles' draft.
The Bucs' draft class is also far ahead in terms of AV (374 to second-place 1995 New England's 314), though it actually comes in second in production for the team that drafted these players: the 1996 Baltimore Ravens, which included Hall of Famer Jonathan Ogden and future Hall of Famer Ray Lewis, got 52 more points of AV, and the 1995 Bucs' class, the one with Hall of Famers Derrick Brooks and Warren Sapp, 25 more points.
