I guess I should have been more clear (or else I didn't clearly understand RR2's comment).

When I read that "1996 is ancient history in NFL terms because there are no one on that team who is also on this team's roster. You're comparing apples and oranges", I labored under the impression that this meant that there is no one on "this [Ravens] team's roster" who was also on the 1996 [Ravens] roster.

A quick check of the nfl.com site indicates there was some guy named Lewis on both squads.....

Sorry for the confusion.
