Flex Help - Need highest upside

Ok, I’m going against the Gurley team who is just dominating and need high upside guys to take him down.

Two flex, so pick two:
Christian Kirk
Sterling Shepard
Marvin Jones

Thanks for the help guys

In a Full PPR I go with Kerryon and Jones. If You dont want to double up on lions i would do Kearse for Jones I think Kerryon has a good week.

Oh shoot, it’s half PPR. Same advice?
