I made the awful error of starting J McKinnon and V Davis this week ... we're highest ranked on 4for4 and Fantasypros composite of top 5, but ...
I am in a hole and need the highest upside flex amongst:
Ajayi v CHI (looks good, but gets very few touches in a crowded backfield)
Ertz v CHI (seems like his hammy is still bothering him)
Fitzgerald v JAX (no Ramsey, but jags still tough def)
Collins v HOU
Who has biggest upside ?
Collins and Ajayi, in that order if you're looking at pure upside. Fitz and Ertz, in that order if you want to be a little safer. Good luck!
