We're a Buffalo Bills blog. We should know better than anyone which Bills players are in line to be productive fantasy plays in Week 5, right? We'll test the theory each Saturday for the remainder of the season, at any rate. Here we go.

QB Ryan Fitzpatrick. Put up big numbers in Weeks 1-3, but was held without a passing touchdown for just the second time under Chan Gailey last week in Cincinnati. Fitzpatrick should improve this week, but Philadelphia can pressure him much the way Cincinnati did. Keep him benched if you can.

RB Fred Jackson. Jackson has emerged as one of the NFL's best running backs this season, and a must-start in fantasy. He's got a terrific matchup against Philadelphia and their linebacker-weak No. 30-ranked run defense. It's fair to expect big numbers this week.

RB C.J. Spiller. We imagine Spiller's still on plenty of rosters. He barely plays. Keep him on the bench.

WR Stevie Johnson. Even in a down week at Cincinnati, Johnson has been a consistent producer. He's still a must-start in fantasy, and shouldn't have problems getting himself open on Sunday against Philly's hyped corners. Whether the ball is there, however, is another question entirely.

WR Donald Jones. Jones has had trouble getting into rhythm with Fitzpatrick this season. He's best at finding holes in zones, but Philly will play man coverage on him on the outside. Jones may really struggle Sunday.

WR David Nelson. A fantasy darling at one point this season, Nelson has just two receptions for 18 yards in his last six quarters of play. He's a guy that Philadelphia can scheme to take away - but he can also do some serious damage against Philly's underneath zones. He's got more potential for numbers than Jones, but we'd still advise sitting him until he's back on track.

TE Scott Chandler. Still a threat in the red zone, but not really anywhere else, Chandler has seen his playing time decrease in recent weeks. You're taking a risk starting him this weekend.

Bills Defense/Special Teams. The potential for turnovers exists; the Bills lead the NFL with eight interceptions, and Philadelphia has one of the worst turnover margins in the NFL. Still, Philly also has the potential to put up big yardage - and potentially a lot of points - against a Bills defense that's struggling to stop the run and pressure the quarterback. Again, this is a volatile play; insert at your own risk.
