Which 2 should I start this week? Donald Driver, Greg Jennings, Larry Fitzgerald, Brandon Marshall.?

Fitz is a must start every week. The Seahawks give up a lot of big plays, but you never know which Packer WR is gonna make them. Marshall is playing against a tough D, but the Broncos will be throwing the ball a lot, and will also make sure he gets plenty of looks. I'd use Marshall along with Fitz. Good luck.
