I would temper your optimism about Flynn's potential impact on the Packers this season. An elbow injury has played a role in his departures from three NFL teams in the 2013 calendar year, and it's safe to say that a quarterback-starved league wouldn't have left him available all week if it thought he were capable of his performances in 2010 and 2011.
When you're in an emergency, as the Packers are, the value of a player who knows your offense rises.
But actions are the only truth we can rely on in the NFL, and the league's collective apathy about Flynn at the moment tells us pretty much what we need to know.
