Willis turned limited playing time into a contract and a starting role, but the ripple effects extend beyond Miami. Here is a buy, sell, and deep stash after Malik Willis signed with the Dolphins.

Buy: QB Kyler Murray

Now that Malik Willis is officially a Miami Dolphin, a move most people saw coming, it opens the door for Kyler Murray to become the most sought-after quarterback remaining in free agency. There are still several teams (MIN?) in need of a starting quarterback, and someone with Murray's upside should draw plenty of interest.

We sometimes forget how productive Murray has been when healthy. Injuries have limited him in recent seasons, but in the years he played full schedules he consistently finished as a fantasy QB1. Yes, the injury history is a concern, but the league always finds room for quarterbacks with Murray's talent. Last season alone we saw 44-year-old Philip Rivers and 41-year-old Joe Flacco start games.

Murray is also a more intriguing fantasy option than Tua Tagovailoa because of his rushing upside. He adds a dimension that many quarterbacks simply don't offer. Murray has also been relatively protective of the football, carrying a career interception rate of 2.0%, slightly better than the league average of 2.2%.

When healthy, Murray is a starting quarterback in single-QB leagues and even more valuable in Superflex formats. His value remains depressed because he doesn't currently have a team, but that is likely to change soon. Even if it doesn't happen immediately, he can still be acquired for roughly a second-round rookie pick. If you draft a quarterback in the second round of rookie drafts, you're hoping he earns a starting job at some point anyway. Look at Jalen Milroe last season.

Sell: RB De'Von Achane

De'Von Achane is one of the most exciting players in the league. No one will deny that. His speed and elusiveness make him a threat to score any time he touches the ball.

The concern now is how often he will actually have the ball in his hands. I previously wrote that Jeff Hafley and Bobby Slowik prefer a pass-first offensive approach. That was already a slight concern for Achane, but pairing that with Malik Willis could make it more noticeable.

In Willis' last five starts, he threw only 10 passes to running backs. The common assumption is that inexperienced or struggling quarterbacks rely more heavily on checkdowns, but that hasn't really been the case with Willis. If that trend continues, it could limit Achane's receiving opportunities.

Half of Achane's fantasy production has come through the passing game, so any decline there could impact his weekly ceiling. Achane still carries massive dynasty value thanks to his age (24) and big-play ability. He already has multiple 20-point fantasy performances and remains one of the most explosive backs in the league.

Because of that, his value is still extremely high in dynasty leagues. This creates an opportunity to tier down at running back, gain additional assets, and potentially replace much of his production with a more balanced roster build.

Deep Stash: QB Quinn Ewers

I'll be blunt: I'm not convinced Malik Willis is a long-term NFL starter. He hasn't looked like one through his first four seasons, and I'm not sure that suddenly changes in Miami.

This signing makes some sense because Hafley has familiarity with Willis from his time in Green Bay. However, it also raises the possibility that the Dolphins may not be pushing all-in to win immediately. If Willis struggles or gets benched, the Dolphins could turn to second-year quarterback Quinn Ewers.

Ewers was an interesting prospect coming out of Texas last year. In his final college season, he threw 33 touchdowns and looked far more comfortable operating within the offense. As a rookie, he saw very limited action but did start the final three games of the season.

During those starts, Ewers threw three touchdowns, matching Willis' season total. It took him 75 attempts to get there, but there were flashes of potential. His best performance came in Week 17, when he threw for 172 yards and two touchdowns without an interception.

Ewers probably isn't a long-term NFL starter, especially on a roster like Miami's. However, having a potential future starter on your bench or taxi squad can save you from burning FAAB or waiver priority later in the season. He's dirt-cheap right now and often sitting on waivers, making him a very low-risk stash in deeper dynasty leagues.
