I have 3 options for my flex, Carlos Hyde against Steelers, Devonta Freeman against Eagles or Marvin Jones against Jets in the flex. I'm wary of Freeman's matchup.
marvin jones for me - he could literally win your fantasy week for you - he always has a game early in the year that makes me love him and i can see it happening vs the jets corners
now that's just me personally - if im honest at this point you just play the best player rather than the matchup because you never really know the strengths of different teams in week 1 so id honestly just play the best playmaker which is probably devonta freeman (who's the more likely of the 3 to score tds too)
i like hyde the player but its too early on a new team to really know what his role or his effectiveness is gonna be
objectively id play freeman
personally id take the risk on jones
