Looking for an all-time roster

I'm a statistician and researcher for the Buffalo Bills. We're trying to get an idea of which Bills played at any time in the CFL, and have been successful in acquiring all-time rosters for all teams but the 'Riders. Does anyone have that information handy or know where I can get it? (The team has not responded to my requests for a media guide, and I get the impression that the all-time roster isn't in it anyway...) Help!!!

Contact the Rider store and ask to purchase a fact book. If they don't have a 2005 edition left over, the new one should be out by mid season. It has the all time roster listed. You can get the contact info at Riderville.com
