Case Keenum, Quarterback, Los Angeles Rams

It's not really recency bias that has us suggesting Keenum could be a decent waiver-wire add this week. At least, recency in looking at Sunday's performance. 

The stopgap Rams' starter took advantage of a disastrous Detroit Lions defense, completing 27-of-32 passes for 321 yards with three touchdowns and one interception in a 31-28 loss. In a vacuum, we might be able to chalk this up to one mirage of a performance. 

Though, Keenum has done extremely well statistically over the past several weeks. Including Sunday's performance, he's averaging over 250 passing yards with eight total touchdowns in his past four starts. The recommendation here surely isn't to pick him up to start immediately. Instead, it's to give you a decent bye-week and injury replacement, and someone that's almost guaranteed to start for the remainder of the year. 

Marcus Mariota, Quarterback, Tennessee Titans

After some early-season struggles, it's readily apparent that Mariota has taken off during his sophomore campaign. He completed 20-of-29 passes while collecting four total touchdowns against the Miami Dolphins last week. The former Heisman winner followed that up by tallying 348 total yards and four touchdowns against the winless Cleveland Browns on Sunday. 

With games coming up against the questionable defenses of the Indianapolis Colts and Jacksonville Jaguars over the next two weeks, Mariota is a fantastic potential add. In fact, he's someone you might even consider streaming over the next two weeks. That's how good he's played. That's how bad his level of competition is over the next two weeks. 

Jay Ajayi, Running Back, Miami Dolphins

Even with Arian Foster returning to the field on Sunday, it was Ajayi who dominated against the Pittsburgh Steelers. The second-year running back put up 204 yards and two scores on 25 rush attempts. It was by far the best performance of his young career. And it sets into motion he possibility that Ajayi, who was a healthy inactive for Week 1, will be able to shoulder the workload for Miami moving forward. 

Zach Zenner, Running Back, Detroit Lions

With Ameer Abdullah lost for the season and Theo Riddick banged up, Detroit had to look in another direction Sunday against a good Los Angeles Rams defense. Some figured it would be the recently signed Justin Forsett that would get most of the touches. It didn't work out that way. Instead, Zenner jumped into the primary ball-carrier duties. He responded by putting up 77 total yards on 16 touches. While Detroit's passing game is clicking on all cylinders with Matthew Stafford, it's going to want to continue creating balance on offense. If that's the case, Zenner becomes a tremendous waiver option. 

Cameron Meredith, Wide Receiver, Chicago Bears

Coming off a nine-catch, 130-yard performance against the Indianapolis Colts last week, the key for this second-year receiver was to prove that it wasn't a fluke in Week 6. That's exactly what he did. Finding a nice connection with Brian Hoyer, this Illinois State product caught 111 passes for 113 yards on 15 targets. That brings his two-game total to 20 receptions on 27 targets for 241 yards and a score. Needless to say, Meredith has now proven himself to be a viable waiver-wire pickup and a potential must start from the get-go. 

Michael Thomas, Wide Receiver, New Orleans Saints

With Drew Brees now on pace for over 5,500 passing yards, it's readily apparent that anyone he decides is going to play a huge role on offense will put up the necessary stats to make a fantasy impact. After Sunday's performance, this rookie from Ohio State is surely one of those guys. He cauht all five passes thrown in his direction or 78 yards and a score against the Carolina Panthers on Sunday. Thomas has now cauht 26-of-36 targets for 307 yards and three scores in five games. 

Coby Fleener, Tight End, New Orleans Saints

The same thing we said about Thomas can be applied to Fleener. And in reality, it might be a bit more magnified here. Fleener signed a huge free-agent deal to play a Jimmy Graham-like role for the Saints. But through the first two games, he struggled big time. The veteran caught just 3-of-12 passes for 35 yards. Since then, it's been a completely different story. Including Sunday's 74-yard performance, Fleener has caught 16-of-23 passes for 202 yards and two touchdowns in three games.
