Bradshaw and Austin for Martin and Nelson

[Vobs56]

Would Ahmad Bradshaw and Miles Austin for Doug Martin and Jordy Nelson be a good trade for me? I am very thin at RB but could probably afford to downgrade at WR to do so. He also has Torrey Smith and Danny Amendola at receiver.

My current roster:
QB-Peyton Manning
WR-Roddy White
WR-Steve Smith (Car)
RB-Chris Johnson
RB-Ahmad Bradshaw
Flex-Miles Austin
K-Robbie Gould
DEF-Dallas
BN-Matt Schaub
BN-Lance Moore
BN-Andre Brown
BN-Denarius Moore
BN-Jonathan Stewart
BN-Mark Ingram
