FLEX help for title game

Okay folks. What to do with my FLEX?? Standard scoring. Currently running Aaron Jones and Austin Ekeler in my RB spots and Julio Jones and Davante Adams in my WR spots.

My FLEX options are as follows:

Raheem Mostert vs LA

Tyler Boyd @ MIA

Michael Gallup @ PHI

Terry McLaurin vs NYG

Breshad Perriman vs HOU

James White vs BUF

I’m leaning Mostert for the guaranteed touches and workload over a bunch of WR. But some of those WR have good matchups and high ceiling potential. Guy I’m playing has averaged the 2nd most league points per week over the last 6 weeks so I do need the points. Thoughts?

BONUS: Tannehill against vs NO or Ryan vs JAX?

Bump for any help
