I don’t see a post on this thread in which anyone is hinting Tolzien is a superstar. (Also, IMO that comment disrespects serious Packers fans on this forum.) I see comments like he’s better this year than Hundley and he’s better than he was when he first joined the Packers.
As I previously posted, Tolzien was signed to the Packers practice squad on September 1, 2013. He stayed on the PS for 65 days until after Rodgers got hurt vs. the Bears. It's safe to say he received no snaps with the first team offense during that time. He spent 6 days on the active roster preparing as Wallace’s backup before entering his first game as a Packer against the Eagles. He then prepared for 6 days as the starter for the Giants game. That would certainly be a factor in how he played, wouldn’t it?
As to bouncing around several teams PS, an article I linked in this thread sheds some light on that: So after bouncing around other teams, McCarthy & Co., who know a little something about QB play, observed he was deficient in his release point, footwork and throwing mechanics. That more than hints at the possibility that the other teams didn’t do much of a job coaching him. He’s now immersed in the Packers’ offense and he’s physically better. The most impressive thing about this preseason was the way he ran the no huddle. That probably has a lot to do with why he’s the backup and not Hundley, who I expect to be the backup QB next season.
No one said he’s a superstar. I think it’s likely he’ll be playing elsewhere next season. But basing an evaluation of Tolzien on how he played just after arriving in Green Bay two years ago is shortsighted.
