During his time under Adam Gase, Ryan Tannehill posted above average marks in Yards per Attempt, Completion Percentage, and Touchdown Percentage. In contrast, Sam Darnold has been greatly below the league average in each of these statistics while playing under Gase. Both of these players suffered from low passing volume. The real difference is that Tannehill was able to make the best of his opportunities while Darnold has wasted them.
Sam Darnold is being drafted as a fringe top 100 player in SuperFlex startups. Despite producing fantasy production comparable to a mediocre wide receiver, he is still being priced near much more effective quarterbacks, and that can be used to gain value. If there is another manager who believes that there is hope for Darnold to have his breakout season, now is the time to cash in.
