Not NFL, but former WIU QB Sean McGuire (who had tryouts with the Vikings and Dolphins) was signed by the Winnipeg Blue Bombers (CFL). He'll be competing for a spot there with former USD QB Chris Streveler.
I wish more players like that would go straight to Canada. He could have a solid career there or if he does well enough maybe get a real shot in the NFL. With the XFL now formed these guys have an alternative in America that will last for at least one year.
