But this weekend may be the toughest slate of games to pick all season. All three contests could go either way.
So we brought in special reinforcements. The AFC North blog summoned Facebook friend Amanda Blasik for help with our Week 15 picks (all times are ET):
New Orleans Saints (10-3) at Baltimore Ravens (9-4), Sunday at 1 p.m.
Blasik's comment: The Saints are going to pass on every down and wear the Ravens' defense down just like Houston did last week.
Walker's score: Saints, 27-24
Blasik's comment: The Bengals have better personnel than the Browns, and Colt McCoy will be a little rusty coming back. As much as I love to see the Bungles lose, this streak has to end sometime, right?
Walker's score: Bengals, 17-16
Blasik's comment: Steelers QB Ben Roethlisberger will be able to create more on offense than Mark Sanchez will against the Steelers' D, even if Troy Polamalu is out. Ryan Mundy and/or Will Allen will be a better replacement for him than Tyrone Carter was last year.
Walker's score: Steelers, 16-13
Last week: 2-1
Comment: Thanks for the help, Amanda! The AFC North blog might go 3-0 this week.
