[Deathstar 80]

These are the present quarterbacks on the Vikings roster:

Tarvaris Jackson - Entering his 4th season. To my understanding, he's the projected starter. According to this injury, he might not be. He improved to a 9:2 touchdown:interception ratio last year, but I believe Coach Childress complained that Tarvaris wasn't making enough "risky" moves like he wanted Tarvaris to do (so he put him on the bench).
Average QB ranking for last year: 95.4

Sage Rosenfels - Entering his 9th season. Has a 6:10 touchdown:interception ratio, but he made up with his high percentage throws. (His worst game last year (Played for Houston Texans) was against a good Baltimore Ravens defense, which is debatable since he threw for 294 yards)
Average QB rating for last year: 79.5

John David Booty - Entering his 2nd season. Never played in a regular season or post season game.
Average QB rating for last year: (Preseason) 36.9

If I had a choice (even with Michael Vick as an option), I would pick Sage Rosenfels. If you look at Tarvaris Jackson, he had a good rating for last year mostly because he faced easy defenses (such as Arizona Cardinals and Detroit Lions). Sage Rosenfels had to face a good Baltimore Ravens and a good Minnesota Vikings defense (And he had a 103.2 QB rating at the Minnesota Vikings stadium!).

Also, Tarvaris Jackson now has a nagging knee injury. I would at least give him some rest. And for those who think the Vikings are going to be worse, I personally think they're the exact same seeing that Sage Rosenfels is their quarterback (and also the quarterback has a much lesser role for the Minnesota Vikings anyway since they have Adrian Peterson).
