I think I would go with Jackson, based on the matchup and hope his speed plays a big role. I don't think Johnson is a good bet considering he'll be battling Bailey and his possible injury setback.
Seems the rankings I'm looking at disagree with me, though. Tough call.
QB Matthew Stafford, Michael Vick, Jay Cutler
WR Calvin Johnson, Miles Austin, DeSean Jackson
WR Jeremy Nelson, Torrey Smith
RB Ryan Mathews, Darren McFadden,
RB Darren Sproles, Mikel LeShoure
TE Vernon Davis
K Justin Tucker
