FLEX Week 12 Needed Please -- Griffin, Gage or C Samuel?

Full PPR. I also have Slayton but not considering him because the matchup’s too tough. If it helps, I have Julio in my lineup already. Currently 7-4, in 4th place in a 12-team league with 6 playoff spots, should clinch a playoff bid with a win this week – pushing for the 2 seed and a 1st round bye and outside chance at the top seed. Thanks in advance.

bumping please
