Mendenhall for Thomas?

[chrambrose]

Was just offered Mendenhall for Demaryius Thomas. Any thoughts? Should I try to get a more proven RB from another team?

I'm really hurting at RB, however I don't know if I can trust that Mendenhall will continue to perform.

My RBs:
Charles
Donald Brown
Pierre Thomas
Woodhead

WR:
Percy Harvin
Demaryius Thomas
Marques Colston
Hartline
Boldin
