Case Keenum is coming off a dud, scoring a measly 5.68 points at Baltimore last week. But with a home date against the Kansas City Chiefs, he's in a great spot for a bounce-back outing.

As good as Patrick Mahomes and the KC offense has been, the Chiefs' defense has been pretty awful, ranking as the league's worst D by our metrics. They are allowing the second-most fantasy points to opposing quarterbacks, with Jimmy Garoppolo's 22.34-point day in Week 3 being the fewest fantasy points they've given up to a starter this season.

Vegas is fully on board with the Kansas City offense, giving them Week 4's highest implied total, at 30.25, and making Denver a 4.5-point home underdog. The matchup boasts a week-high 56.0-point over/under, and Denver's 25.75-point implied total is a number we can feel good about.

In a game where the Broncos will likely have to throw to keep pace, Keenum is an appealing streamer. We peg him to score 17.84 points, making him our QB15 for the week.
