Week 5 at Chicago Bears
Case Keenum went wild against the Bucs in Week 3, but came crashing back down to Earth in Week 4 vs. the Lions. The Minnesota QB threw for 219 yards and 0 touchdowns, which is rare to see in this age of football. So far, Keenum has had two poor games in his three starts with his only big performance coming against an injured defense.
His matchup this week against the Bears isn't a tough one, but considering his performances so far, it's hard to trust him as a fantasy option. It's also worth noting Sam Bradford returned to practice in a limited fashion on Thursday. Since the Vikings play Monday night, it could turn in to a late decision.
Even if Keenum does play, he's not a strong QB option this week.
