Buckley named as the backup in Calgary and possibly Brandon Bridge as the backup in Sask.
These guys EARNED their spots on the roster, they weren't hired to fill a roster quota. They made the team because they were better than other QBs out there, good for them. I'm sure either could be a starter some day.
The QB position is the most important on the team and it should always be the best player for the job and there should never be any rule that favours a national QB.
