Rosencopters Job to win

With Favre Officially out of the picture the Vikings now have themselves a QB battle brewing at training camp. Former Houston Backup Sage Rosenfels and the incumbent Tavaris Jackson. I liked to watch Sage play when he was in a Texan uniform and think that he will take the job away from Jackson and start week 1. What do y'all think? Do you think Sage is good enough to be a starter for the entire season?
