Don't forget, Cook is back this week too. Vikings were ranked 8th best against the pass through the first half of the season, after that (and Cook getting injured) they've dropped to 23rd. Granted, the schedule did get harder, but that's worth noting also. Teams don't throw Cook's way a lot. Not saying that'll equate to turnovers, but hopefully Schaub won't be able to just do whatever he wants all day.
And about Percy, I have a strange feeling he's played his last game as a Viking. With them never out of the playoff race, it was just odd that they shut him down for the season right away over an ankle injury. Plus he was demanding trades in the offseason and voicing displeasure. Match that with Ponder's poor play and him getting into it with Frazier and who knows. Just got a gut feeling. Hopefully I'm wrong.
Whether they lock him up I think they have to go after a WR in free agency. The draft is cool and maybe they can grab one there too but we need a guy in here ASAP. Jennings looks like he's about to be done in Green Bay after this season and the Vikes do have a history of grabbing ex Packers
Kalil, Smith, Robinson was a great first three draft picks last offseason. Hopefully they grab some guys this offseason with high picks that can come in and contribute right away also. I think wide receiver and linebacker will be the biggest areas of focus. Possibly a DT also.
