Lineup help, had kamara need advice

Standard scoring, had kamara and Michael Thomas go already. Planning to roll with Keenan Allen in wr2 spot and Fitzgerald in flex.
Should I play cousins or Ben Roth
And in rb2, I have latavius, demarco, Derrick Henry. Or could grab gio, drake, barber, Davis.
Concennsus rankings suggest drake, then latavius then demarco

Big Ben over Cousins

follow the rankings, Demarco is boom or bust, Henry is nearly a non-factor with Demarco there so they cancel eachother out.

Drake
Latavius
the rest are all about the same.
