Pete Prisco's Week 4 NFL picks: Ravens cool off unbeaten Bills, Packers hand Vikings first loss

Pete Prisco reveals all his Week 4 picks, including the Bengals' must-win in Carolina

Is picking NFL games tough this year or what? Not just against the spread either.

I was 7-9 straight-up last week after all the uncertainty of Week 3 that saw upsets galore and survivor pools get blown up. That dropped my straight-up record to 24-24, which tells you how crazy this season is so far. I am .500 straight-up? What the heck.

Against the spread, it was even worse last week. I went 6-10 to drop my record to 23-22-3. At least I am over .500 for the ATS picks. By the way, that record is tied for the lead in our CBSSports.com expert picks. Some experts we are.
