Flex help pick 2 positions

Pick 2 flex 0.5 ppr

Full disclosure I’m leaning towards
Boyd vs Tampa bay and
Lamar Miller vs Miami

Other options are
Sanders vs kc,
Chubb vs Pittsburg
Landry vs Pittsburg

Thanks

I prefer sanders vs KC to both of those, and i am probably even between Miller and Landry. Boyd i think has a lower floor and higher ceiling than the rest. So he wold be fine just a little more risky.
