I have 1 Foex spot available in standard scoring
My options are
Fuller
Latavius Murray
Flex Dilemma
Generally in situations like these I lean towards the RB cuz in a goal to go situation he’s got the better odds of a TD. That said, Fuller has a much higher floor. Depends on your lineup; if you want a safe but gross floor then go with Murray but if you are cool with a potential bust go with Fuller.
^I would follow that advice. If your team is projected to lose by more than 10, fuller.
