Need help in my FLEX! PLZ!

Hello all,

I’ve got a few options to throw in my FLEX position in my standard league.
-Diggs
-Crowell
-Morris
-Burkhead

I am leaning toward Diggs because my opponent is playing Case Keenum this week.

Thoughts please?

I would go Diggs as well. Especially in a PPR. Diggs has elite WR1 upside every week
