I've seen that site posted a bunch of places, but I don't understand why. It doesn't list uniform numbers, height, weight, or anything remotely useful in identifying which players are which.
I have done a few starting with the 02 Raiders all the way to the 88 49ers but there are a few players on some rosters I just cannot figure out who they are. Maybe if I post them you guys can help me figure out who the players are that are missing and help me correct the players that I may have gotten wrong. PM me if you are interested in helping I would like to get all the teams done sooner or later.
