Week 1 featured plenty of big scorers and massive flops. Tyreek Hill had two receiving touchdowns and added a 90-yard return touchdown on his way to an absurd fantasy game. Ryan Fitzpatrick, filling in for the suspended Jameis Winston, scored 41 fantasy points in ESPN standard scoring! He had four passing touchdowns, 417 passing yards, and a rushing touchdown. Meanwhile, stars like Ezekiel Elliot and DeAndre Hopkins struggled against strong defenses. But there were also several under the radar players who proved they are worthy of roster status.

Let's take a look at those must-add waiver wire pickups.

1. Miami Dolphins RB Frank Gore (11.7 percent Ownership)

Most people assumed that Kenyan Drake would be the lead back in Miami. Instead, it looks like Kenyan Drake and Gore will be splitting the carries. Gore averaged more than 6 yards per carry in his first game (9 carries for 61 yards) in week 1 and should be viewed as a must-add player from the waiver wire.

2. Denver Broncos RB Philip Lindsay (1.9 percent Ownership)

Fellow running back Royce Freeman attracted more fantasy attention after earning the starting job in the preseason. Lindsay proved in week 1 that he should not be ignored, as he had 15 carries for 71 rushing yards and two catches for 31 yards and a touchdown.

Moving forward, Lindsay will likely have timeshare status in what should be a potent Denver rushing attack.

3. New England Patriots WR Philip Dorsett (4.6 percent Ownership)

Without Brandin Cooks, Tom Brady had to throw the ball to somebody other than Rob Gronkowski. Most fantasy players believed that receiver would be Chris Hogan, but now it's starting to look like Dorsett could be the guy.

He had seven receptions for 66 yards and a touchdown and outshone Chris Hogan, who had just one catch for 11 yards.

4. Seattle Seahawks TE Will Dissly (0.1 percent Ownership)

The fourth round rookie was only supposed to block for the Seahawks but ended up catching three passes for 105 yards and a touchdown against the Broncos in week 1.

Russell Wilson likes to throw the ball to his tight ends, and Dissly is worth a speculative add from the waiver wire after his impressive week 1 debut.

5. Denver Broncos QB Case Keenum (12.8 percent Ownership)

Against the Seahawks, Case Keenum proved that he is willing to sling the ball. He threw for more than 300 yards and three touchdowns and ended the game with 19 fantasy points. He did throw three interceptions, but Case did prove that he is capable of putting up solid fantasy numbers as the Broncos starting quarterback.

6. Jacksonville Jaguars RB T.J. Yeldon (7.9 percent Ownership)

Leonard Fournette suffered a hamstring injury against the Giants. The severity of the injury has not yet been determined, but if Fournette misses any significant time, Yeldon steps into a role where he will receive a significant number of touches.

Add Yeldon from the waiver wire, especially if Fournette is on your roster.

7. Philadelphia Eagles RB Darren Sproles (9.4 percent Ownership)

Lost in Jay Ajayi's big game against the Falcons was the fact that Sproles will be involved in the Eagles offense. He ended the game with just 3 fantasy points, but Philadelphia will likely utilize Sproles as the running back in passing situations, making him worth a waiver add, especially in PPR formats.

8. Seattle Seahawks WR Brandon Marshall (5.7 percent Ownership)

With Doug Baldwin sidelined, veteran wide receiver Brandon Marshall stepped up and caught 3 passes for 46 yards and a touchdown. With Baldwin unlikely to play in week 2, Marshall has become a must-add player and could certainly have some value moving forward.
