James White & Geranamo for AB in full PPR?

12 team Full point PPR - We start 2 RBs, 3 WRs and 1 Flex (any position except QB). I am considering sending James White (my current flex) and Geronimo (my current #3WR slash replacement WR) for AB.

The guy needs RB help badly (he’s starting Henry and Collins)!
my RBs are DJ, Howard, Breida, Royce Freeman and Shady. My WRs are Diggs, Alshon, Marvin Jones and Cobb, and Geronimo.
