I used to put in the rosters every year since gobison.com didn't have them available and then, when they did put up roster information, they didn't update player stats until the season was over. However, gobison.com has improved markedly in that regard (although player stats in their bios still don't get dynamically updated) and they have added roster information for past seasons back to 2004 - makes me wonder if they'll keep adding prior year information.
