Using only a one or two year sample is an odd way of looking at it. Every single CFL QB spent time developing on a team somewhere, if they didn't the league wouldn't have any. Toronto, Saskatchewan, Edmonton, Calgary and BC. Each of those teams has brought at least one QB in to the CFL in the past 5 to 10 years - who is now a starter somewhere.
If you think that doesn't matter, that's okay with me, by the way.
