David Montgomery, Woody Marks both go right into the shaky flex category... both of them need a touchdown in order to have any sort of like floor for fantasy... David Montgomery gets like a few more snaps than Woody Marks does... They do have his anytime touchdown line at minus 110 compared to what he marks at plus 150.

STACKED’s take

Negative signalProjection

Shaky flex; touchdown-dependent despite decent volume projection vs. Tennessee.

Placed in the shaky flex category and needs a touchdown to have any floor for fantasy. Gets a few more snaps than Woody Marks but hasn't shown much juice; offensive line run blocking has been awful. However, with CJ Stroud and Nico Collins returning, the Texans can dictate game script against Tennessee, so Montgomery could see decent volume. His anytime touchdown line is at minus 110, suggesting Vegas expects him to get goal-line opportunities, though production has been bleak.
