R. Woods for L. Murray + C. Samuel + J. Jackson

Here is the starting roster I ended up with in my 12-team HPPR auction league.

K. Murray
Carson
Michel
Julio
A. Brown
Vance
R. Woods
R. Anderson
Ravens

A. Peterson
M. Brown
Mattison
D. Samuel
M. Andrews

Is giving up Woods in order to beef up my bench too much? Should I trust myself on the waiver wire? Or would the best matchup from L. Murray/C. Samuel/J. Jackson be a good enough rotation at flex to make up the loss?

Cheers guys.
